A support system for an equipment housing includes a pair of screw-adjustable legs at one end of the housing and a pivoting trestle at the other end. The pivoting trestle is made of two generally U-shaped channel members, one channel member being inverted and inserted or mounted inside the other channel member. The channel members each have side walls, and a bolt extends through apertures in the side walls to pivotally mount one channel with respect to the other. The housing can be made horizontal, i.e., "levelled" by adjusting the effective length of the two legs, and the trestle automatically pivots to accommodate adjustments to the legs. |
