Abstract: A junction box for raceways applicable to a surface, formed by: an integral support base member including (i) a plate member, applicable to the surface and having an edge for fitting to a raceway; (ii) two tubular body members perpendicular to the plate member adjacent apexes having upper ends; (iii) adjustable members adapted to engage another raceway; and (iv) a first member for attachment to a lid member; a cable transfer member including: a structure holding removable sheet members and having a rear wall and a front wall; and being superimposable over the length of a raceway; and a lid member which is a hollow body having side walls and an upper cover and adjacent to house the base member and the cable transfer member.

Abstract: The device includes a support member; a casing; and a closing and covering member. The support member may be attached to an external member and may receive an electrical mechanism. The support member is provided with a coupling mechanism to the casing and this coupling allows access of conductors from a raceway device. The casing is prismatic in shape and is adapted to surround the support member and the electrical mechanism. The casing is provided with a bight in one side wall thereof. The closing and covering member has a wall portion and a hood portion. The wall portion may be attached to the edges of the bight to close it. The hood portion covers a portion of the raceway device. Where necessary, a guide member is attached to a portion of the raceway device and is covered by the hood portion.

Abstract: The device includes an inner frame to be situated on a base section of a tray, being attachable to grooves of the base section. The device also includes an electrical mechanism mounting plate being attachable to the inner frame, as well as being attachable to boxes containing the electrical mechanisms or to the electrical mechanisms themselves and with a retaining device to an outer frame. The latter is attachable to the inner frame which it completely covers and also is attachable to the grooves of the base section.

Abstract: The member or box includes: a slot under which ribs of the tray may be received and which has passages on one side and an aperture on the other side; a retaining member attached to the slot and which is provided with a fold-down tab and a tooth; fingers resiliently attached to the base portion and provided with teeth inserted through the passages and which may retain a rib; and resilient bridges extending on a higher plane above the base portion and facing the tab. The retaining member is movable between a normal inactive position and an active position in which the tooth is inserted through the aperture, retaining one of the free ends of the rib and the bridges retain the fold-down tab.

Abstract: A device for joining trays includes a transverse portion and a sheetlike buttstrap. The transverse portion is flush with a transverse end edge of a lid section of a tray and engages the side walls of a base section of the tray by end walls which may be provided with projections or with hook-shaped legs. The transverse portion has retaining holes and is provided with a center tab extending longitudinally and which is covered by the lid section. The sheetlike buttstrap covers the transverse portion of the device and the part of the lid section covering the center tab. The sheetlike buttstrap is provided with resilient protuberances mating with the retaining holes.

Abstract: An integral box attached to harpoon-shaped projections in the bottom of a channel-like duct member for electrical wiring by way of a fixed appendage and a pivotable locking tab. The latter has a lower portion extending below the base of the box and an upper portion. The lower portion is provided with a retaining appendage for a harpoon-shaped projection and the upper portion is provided with a locking mechanism.

Abstract: Ducting for electrical conductors with a stiffening arrangement formed by stiffening clamps, each of which comprises two or more parts between which there are transverse gaps separating aligned mutually inserted engaging members of both parts; each pair of adjacent parts are connected by lateral flaps attached to each part across a weakened area.The ducting is of the type having a base wall, two side walls having top ends provided with coupling formations, and intermediate longitudinal partition members each provided with an upper terminal formation. The engaging members of the stiffening clamps engage the upper terminal formations of the intermediate partition members; and coupling parts on the ends of the stiffening clamps connect to the coupling formations on the top ends of the side walls.
