Adjustable Coupling Plate
The most widely used device for extra support is the adjustable coupling plate. The adjustable coupling
plate provides a third point of support. The hook can be moved along a slot in the plate to
accommodate trusses with 12- to 28-inch centers. The hook can also be rotated through 360 degrees to
mate with cross braces at any angle. A special hook used with the adjustable coupling plates utilizes a
bolt welded in place of the truss hook fastener. This hook is secured to the coupling plate by a lock
washer and nut.
The adjustable coupling plate can be installed in two locations on VL2C and VL4 luminaires. This
limits the overhang of the coupling plates from the truss, thereby reducing the hazard when moving the
truss during installation and removal.
