ABSTRACT:
A pull-out frame for electric switchgear is provided in the vicinity of its side walls with bolts which serve as pivots or stops of guide rails which can be retrofitted. The guide rails are provided with a keyhole-like opening, the narrower part of which correspond to the diameter of a bolt and the wider part of which correspond to the diameter of the collar of the bolt. The connection of the guide rails to the side walls can be made by shifting the guide rails in the direction of the force of gravity and can be released in the reverse direction. For securing each guide rail in its upright rest position, a latch which extends beyond one leg of the guide rail in fork-fashion is provided which can likewise be retrofitted at the corresponding side wall.
