A nut is threadedly engaged with the bolt so as to secure the block to the lateral beam. A table is rotatably secured to the block by a screw. The table and the block are movable along the channel and are rotatable relative to the lateral beam when the nut is unthreaded relative to the bolt. The table may be rotated relative to the block when the screw is unthreaded relative to the block.
