The fixture (10) for the electrical appts. (9) is located in the body part (4) of the U-shaped rails (2,3). The fixture component for the rails comprises plates (6) attached to the outside of two centered branch parts (5) which in their width direction have long holes to accommodate screws. The body parts (4) of the rails have centrally aligned apertures for fitment of tubes or installation of cables. The free edge of the rail branch part has a fillet (13) extending in the direction of the body part, and is intended for fixation and the body part is such that it is less than the height of the electrical appts. to be installed to an extent corresp. to the thickness of the wall cover plate (14). |
