Fixing method
Screws, through pre-drilled holes — stated in the fourth bullet. No adhesive is offered and no screws or anchors are stated as supplied

Only the Electriduct says which of its figures is the inside of the channel; every other width and height here is printed without saying whether it is measured inside or outside.

The one inside figure

“Channel Dimension: 2 in Dia” and “Exterior Raceway Dimensions: 3.5 in W × 1 in H” — two figures, each labeled. It is the only listing here that separates the channel from the outside, which is exactly the distinction this shelf turns on.

The length that cannot be read

Three raceways and 59 inches, with no word for which one the 59 belongs to. Read as each, the kit holds about 4.5 m; read as the total, 1.5 m. At $59.99 on October 26, 2026 that is either about $13 a meter or about $40, and the highest price of any kit on this shelf.

What is not published

Whether screws come in the box, any end caps, and any corners other than the single 90° turn.

The questions that come up before an order

Is 59 in the length of each piece?

The listing does not say. The first bullet gives Raceway Length: 59 in and the second gives three raceways. If each is 59 in the kit holds about 4.5 m (14.75 ft); if 59 in is the total it holds 1.5 m (4.9 ft).

Why is a flanged half-round profile different?

It is a floor and wall guard rather than a lidded duct: the 2 in channel sits under a raised half-round with flat flanges either side, 3.5 in wide in all, so it can be walked over or screwed along a wall.
