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 nested inside the other. The channel members have side walls, and a bolt extends through holes in the side walls to pivotally mount one channel with respect to the other. The housing can be levelled by adjusting the effective length of the two legs, and the trestle automatically pivots to accommodate these adjustments as they are made.
