Abstract: An angle accessory for skirting ducts includes two flaps mounted to pivot about a pivot axis via assembly structure including two male engagement elements on the first flap and two female engagement elements on the second flap. In the vicinity of the male engagement elements, the first flap has at least one flange projecting from one of its end edges and forming an obstacle that co-operates with at least one lip of the first flap to define at least one passageway giving access to at least one male engagement element, the passageway having a small height constraining the flaps to be assembled together by bringing the second flap towards the first flap while tilting the second flap relative to the first flap's pivot axis, and then by straightening up the second flap along the pivot axis so as to engage successively the female engagement elements over the male engagement elements.

Abstract: The invention relates to an angle accessory for skirting ducts, said angle accessory comprising two flaps mounted to pivot about a pivot axis via assembly means comprising two male engagement elements on the first flap and two female engagement elements on the second flap. According to the invention, in the vicinity of said male engagement elements, the first flap is provided with at least one flange projecting from one of its end edges and forming an obstacle that co-operates with at least one lip of said first flap to define at least one passageway giving access to at least one male engagement element, said passageway having a small height constraining said flaps to be assembled together by bringing the second flap towards the first flap while tilting said second flap relative to the pivot axis of the first flap, and then by straightening up said second flap along the pivot axis so as to engage successively said female engagement elements over said male engagement elements.

Abstract: An apparatus support used for example inside a box may have on each of its opposite sides groove elements for being mounted on the side units of a wireway base when the base has such side units. Associated with the support by way of mechanical fastening element, is a plate having at least two projecting columns, with on the top part of the columns, snap-on elements, and the support correspondingly includes snap-on elements matching the snap-on elements of the plate columns.

Abstract: A box includes a body adapted to be directly mounted on the wall and which has an opening, and a canopy which, extending from the body, corresponding to the opening thereof, is designed to cover locally the wireway, transversely thereto. The canopy is formed by at least two separate telescoping parts, spaced out longitudinally over the wireway.

Abstract: An electrical equipment support is associated with an adapter for fitting it to trunking of nominal width or to trunking of predetermined lower width. The adapter includes two closure flanges which are fitted between the trunking of lower width and the support along a respective portion of the transverse edges of the support. A baseplate is fitted to flank the base section of the trunking of lower width from one of the closure flanges to the other and has an engagement system for fastening the flanges together.
