Fixed by the front face, with the weight and the load both printed

HMF 19-inch 1U shelf, 300 mm mounting depth, 483 × 300 × 44 mm, 16 kg, cage nuts included

The shelf that describes its own installation most precisely — fixing points on the front face, at one rack unit — and publishes its own weight alongside the load it will carry.

Rack units
One — stated in the title and in the fourth bullet, which puts 1 HE in brackets after the description of the fixing points
Mounting depth
300 mm — stated in the title as the installation depth, and in the first bullet as a requirement: the shelf suits 19-inch cabinets offering at least 300 mm of mounting depth
Cantilever or four-post support
Neither term is used, and the fourth bullet describes the arrangement plainly: a quick installation on the profile rails thanks to fixing points on the front face. A shelf carried at the front alone is what the cantilever entry in this table describes, and the listing does not use the word
Stated load rating
About 16 kg — stated in the fifth bullet alongside the dimensions and the weight. The word about is the maker’s own
Vented or solid surface
Not published on the listing — no perforation, no vent and no airflow claim appears in any of the five bullets. The third describes stable steel sheet with a scratch-resistant black powder coating
Sliding or fixed
Fixed — stated in the first bullet as a shelf for fixed installation, and confirmed by the fourth, which describes it bolted to the profile rails
Usable surface dimensions
Not published on the listing — the fifth bullet gives 483 × 300 × 44 mm as the width, depth and height of the shelf, which are outer dimensions. No separate figure for the flat surface appears

On the listing

A shelf for fixed installation in 19-inch network cabinets offering at least 300 mm of mounting depth, one rack unit high, described as allowing tidy accommodation of network components that cannot be rack-mounted themselves; made from stable steel sheet with a scratch-resistant black powder coating; installed quickly on the profile rails thanks to fixing points on the front face; and given dimensions of 483 × 300 × 44 mm in width, depth and height, a weight of 1.44 kg, a load of about 16 kg and cage nuts as the accessory.

Fixing points on the front face

Five of the seven shelves in this hub leave the buyer guessing how they are held up. This one describes it in a single clause.

The fourth bullet: a quick installation on the profile rails thanks to fixing points on the front face, one rack unit.

That is the cantilever arrangement without the word. Everything standing on the tray is carried by two rails at one end, and the further back a load sits, the harder it works the flanges. It is why the figure in the next bullet is about 16 kg, and why the four-post shelf on this shelf can state 110 kg without being made of anything special.

Describing the mechanism in plain language is worth more than the term would have been. The term is jargon; the sentence tells you where the metal is bolted.

Three hundred millimetres, stated as a requirement

The first bullet does not say the shelf is 300 mm deep and leave it there. It says the shelf suits 19-inch cabinets with at least 300 mm of mounting depth.

That is the right way round. A shelf deeper than the cabinet does not go in at all, and the buyer holding a tape measure is measuring the cabinet, not the shelf. On the cabinets hub of this site the depths run from 180 mm to 450 mm, so this sentence rules out the shallowest of them at a glance.

Its own weight, printed

The fifth bullet gives 1.44 kg.

Almost nothing in this hub publishes what a part weighs, and it is a small, practical number. A 1.44 kg tray is a one-handed object: it can be held against the rails with one hand while the other starts a bolt, which is exactly the moment a rack shelf is fitted.

It also puts the 16 kg load in proportion. The shelf weighs a tenth of what it carries, which is a sensible ratio for a cantilever part and would be a worrying one for anything claiming much more.

The surface, undescribed

There is no perforation on this page, and no statement that the surface is solid either.

Four of the seven listings on this shelf name their perforation and say what it is for. This one describes the coating and the steel and never the tray. Under a device that vents downwards, or in a cabinet relying on convection, that is a real difference, and the page leaves it to be discovered on delivery.

The other omission is the usable surface: 483 × 300 mm are the outer dimensions, and the flat part inside the flanges is smaller by an unstated amount.

Before ordering

Check the cabinet offers at least 300 mm, because the listing is explicit that it must. Buy bolts and washers to go with the cage nuts. And if the equipment vents downwards, ask whether the tray is perforated — the page never says.

    StarTech two 1U vented cantilever shelves, 25 cm deep, 20 kg each, tested at 1.5 times load

    The only shelf here sold in pairs and the only one whose maker states a test margin above the rating, at a quarter of a metre deep and twenty kilograms a tray.

    Rack units
    One each — stated in the title and in the first bullet, which describes two 1U vented cantilever rack shelves in a set
    Mounting depth
    25 cm — stated in the title. No minimum cabinet depth is named, and no adjustment range appears
    Cantilever or four-post support
    Cantilever — stated in the title and in the first bullet, and detailed in the fourth as SPCC cold-rolled steel with cantilever front mounting. It is one of only two listings on this shelf to name its support arrangement in words
    Stated load rating
    Up to 20 kg per shelf — stated in the title and in the fourth bullet, which adds that the shelves are tested at one and a half times that load. The test is the maker’s statement and no test document is named
    Vented or solid surface
    Vented — stated in the title and in the third bullet, which describes a perforated 1U tray supporting even airflow and reducing hot spots under servers or audio-visual equipment
    Sliding or fixed
    Fixed — the fourth bullet describes cantilever front mounting, and no bullet mentions runners or any pull-out action
    Usable surface dimensions
    Not published on the listing — 25 cm is given as the depth in the title and no width or surface figure appears in any of the five bullets

  • Stalflex black perforated 19-inch 1U rack shelf

    STALFLEX 19-inch 1U shelf, rear fixing, variable depth, 25 kg

    A 25 kg perforated shelf sold on a rear fixing and a variable depth, with five bullets of description and not one measurement among them.

    Rack units
    One — stated in the title and in the second bullet, which calls the standard 1U and 19-inch format a guarantee of secure mounting
    Mounting depth
    Not published in the title or in any bullet — the title says variable depth and stops there. The manufacturer reference recorded for this listing reads 150 mm, which is a catalogue string rather than a published specification, and no bullet confirms it
    Cantilever or four-post support
    Neither is named — the title states that the fixing is at the rear, which is not the arrangement either of the two named terms describes. No post count and no front-flange description appears in any bullet
    Stated load rating
    25 kg — stated in the title as the carrying capacity. It sits above three of the fixed shelves on this shelf and well below the four-post one
    Vented or solid surface
    Vented — the first and fourth bullets both describe a perforated shelf, credited with improving air circulation and with preventing equipment overheating
    Sliding or fixed
    Not published on the listing — no bullet says whether the shelf is bolted in place or runs on any kind of slide. The fourth mentions mounting equipment to it with cable ties to stop accidental slipping, which is about the equipment rather than the shelf
    Usable surface dimensions
    Not published on the listing — no width, no depth and no surface figure appears in the title or in any of the five bullets
    Fixings supplied
    Not published on the listing — no screws, no cage nuts and no washers are listed. The second bullet says the standard format guarantees secure mounting and names no hardware

  • Tecmojo black vented 19-inch 1U four-post rack shelf with adjustable rear brackets

    Tecmojo 19-inch 1U four-post shelf, 550 mm deep, adjustable 343 mm upwards, 110 kg

    The only four-post shelf in this hub, and the only one that carries three figures instead of one: 110 kilograms, an adjustable depth, and a hardware list counted item by item.

    Rack units
    One — stated in the title and in the first bullet, which describes a 1U four-post server rack tray for 19-inch racks and cabinets
    Mounting depth
    Adjustable — the title gives a shelf depth of 550 mm and a variable mounting depth from 343 mm to 800 mm, while the first bullet gives the same range as 34.3 cm to 80.8 cm. The lower figure agrees; the upper differs between the two, and neither is withdrawn
    Cantilever or four-post support
    Four-post — stated in the first bullet, which calls it a 1U four-post server rack tray designed for 19-inch racks and cabinets with an adjustable mounting depth. It is the only listing on this shelf to name the arrangement in those words
    Stated load rating
    Up to 110 kg — stated in the title and in the second bullet, which names industrial-grade SPCC cold-rolled steel and gives tower servers, uninterruptible power supplies, NAS units and amplifiers as the equipment it has in mind. It is five times the next highest figure on this shelf
    Vented or solid surface
    Vented — stated in the title as a rack tray with ventilation openings, and in the third bullet, which credits the vented design with constant air circulation and effective heat dissipation
    Sliding or fixed
    Fixed — stated in the title as a shelf for fixed installation, and in the second bullet, which calls it a fixed rack tray
    Usable surface dimensions
    Not published on the listing — the title gives the shelf as 550 mm deep and no width or surface figure appears in any bullet
    Fixings supplied
    Sixteen M6 bolts, eight M6 cage nuts, eight flange nuts, two non-slip stoppers and two hook-and-loop cable ties — listed item by item in the fourth bullet, the only counted hardware list on this shelf

    • A hundred and ten kilograms on four posts, five times anything else on this shelf
    • The hardware is listed piece by piece, down to two non-slip stoppers
    • The upper depth figure is 800 mm in the title and 80.8 cm in the first bullet

    Best for: A deep cabinet holding something genuinely heavy — a tower server, an uninterruptible power supply, a stack of drives — where front-only support would not do.

Others worth having spare

  • DIGITUS Cat 6A shielded field-terminated RJ45 plug in nickel-plated zinc

    DIGITUS Cat 6A field-terminated plug, AWG 27/7 to 22/1, cable 5.0-9.0 mm, pack of 10

    The plug here with the widest published sheath window, 5.0 to 9.0 mm, terminated without tools onto solid or stranded conductors alike — and the only one on this shelf to publish an operating temperature range.

    Category rating
    Cat 6A — stated in the title and the first bullet, with transmission to 10 Gigabit per second and suitability for PoE applications up to PoE+, named as IEEE802.3at
    Solid or stranded compatibility
    Both — stated in the second bullet as a toolless termination for solid and stranded conductors, colour-coded to EIA/TIA 568 A and B. The gauge notation carries the same answer: the suffix on 27/7 is a stranded bundle and the suffix on 22/1 a single core
    Shielded or unshielded
    Shielded — stated in the fifth bullet, which names a nickel-plated zinc die-cast metal housing with strain relief and cable fixing providing a 360-degree screen
    Accepted conductor diameter
    AWG 27/7 to 22/1 — stated in the second bullet. The window covers stranded and solid at once because the figure after each stroke is the conductor count. No millimetre figure is given for the conductor itself
    Accepted cable diameter
    5.0 to 9.0 mm — stated in the fourth bullet as the sheath diameters the plug will take. It is the widest of the three outside-diameter windows published on this shelf
    Load bar presence
    Not published on the listing — the second bullet describes a toolless termination with the conductors laid to a printed colour order, and names no separate lacing insert
    Pass-through or standard body
    Neither — the first and third bullets call it a field-terminated plug, assembled without tools for repair, maintenance or joining two installation cables. Nothing describes a crimp, and nothing describes conductors leaving the front
    Pack quantity
    Ten — stated in the title

    • Publishes both conductor constructions and both gauge ends in one notation
    • The sheath window is the widest here, and it is the dimension most plugs leave out
    • Ten plugs at this price is the dearest per end on the shelf after one outlier

    Best for: A repair or a joint on an existing run, where the plug has to go on in place and the cable might be either construction.

  • Mr. Tronic Cat 6 STP RJ45 crimp plugs, 8P8C, from a hundred-piece pack

    Mr. Tronic Cat 6 STP crimp plug, 8P8C, pack of 100

    The emptiest listing on this shelf: a hundred shielded Cat 6 plugs described across five bullets that never once give a gauge, a diameter or a conductor construction — the three things that decide whether a plug fits a cable.

    Category rating
    Cat 6 — stated in the title and in four bullets, with Cat 5 named in the third among the cables it is offered for. No frequency and no standards reference appear
    Solid or stranded compatibility
    Not published on the listing — neither construction is named anywhere in the title or the five bullets, on a plug offered for patch cable and for ADSL and modem leads in the same sentence
    Shielded or unshielded
    Shielded — stated in the title as Cat6 STP. The bullets never return to it, and nothing describes how the body meets the cable screen
    Accepted conductor diameter
    Not published on the listing — no gauge and no millimetre figure appears. It is the only plug on this shelf with neither
    Accepted cable diameter
    Not published on the listing — the outside diameter is never given, and the bullets describe the plugs as durable and low-loss instead
    Load bar presence
    Not published on the listing — the second bullet says the wires are passed through the plug and clamped, and no insert of any kind is named
    Pass-through or standard body
    Not published on the listing — the second bullet describes feeding the wires through the plug, which is how a pass-through body is normally described, but the term never appears and nothing says the conductors are trimmed flush at the front. The plug is called a crimp connector throughout
    Pack quantity
    One hundred — stated in the title and in the fifth bullet

    • A hundred shielded plugs is a quantity that covers a whole installation with spares
    • The 8P8C position count is printed, which two listings on this shelf leave out
    • No gauge and no diameter of any kind, so the cable cannot be matched before ordering

    Best for: A buyer who already knows this plug fits the cable in front of them, and is reordering rather than choosing.

  • VESVITO shielded Cat 6 RJ45 crimp plug in grey with an insertion guide and boot

    VESVITO Cat 6 STP crimp plug, AWG 24-27, conductors 0.9-1.1 mm, pack of 20

    A shielded crimp plug that gives its conductor window in millimetres as well as in gauge, takes solid or flexible conductors alike, and states in capitals that it is not for Cat 7 or Cat 7A installation cable.

    Category rating
    Cat 6 — stated in the title and the first bullet. The second bullet extends the cables it will terminate to Cat 5e and Cat 6A network, installation and patch cable at AWG 24 to 27, and to Cat 7 patch cable at AWG 27
    Solid or stranded compatibility
    Both — stated at the end of the second bullet as suitable for rigid or flexible conductors
    Shielded or unshielded
    Shielded — stated in the title and the first bullet, with gold-plated contacts and a grey boot. The second bullet says it will terminate screened or unscreened cable
    Accepted conductor diameter
    0.9 to 1.1 mm over the insulation, AWG 24 to 27 — both stated in the second bullet. It is one of only two plugs on this shelf to publish a conductor diameter in millimetres
    Accepted cable diameter
    Not published on the listing — the outside diameter of the sheath never appears, although the boot supplied has to pass over it
    Load bar presence
    Supplied — an insertion guide is included with every plug, twenty in the pack, and the first bullet names it as what makes assembly easier
    Pass-through or standard body
    Standard — the plug is named as a crimp connector throughout, and nothing describes conductors leaving the front of the body
    Pack quantity
    Twenty plugs, twenty insertion guides and twenty boots — stated in the fourth bullet as the contents of the packet
