The FiberRunner QuikLock Adjustable Cabinet Bracket is used to support the 12x4 system from any new 0.5 inch threaded rod which is extended down directly from the ceiling, the grid, or a ladder rack system. It features two-position height adjustments to accommodate systems with or without a hinged cover. The adjustable cabinet bracket is secured to the threaded rod with two nuts. The pre-assembled slide clamps enable fast assembly to the channel.
