The SMACNA Testing and Research Institute verified the Strut Gripper from Griplock Systems is an easy-to-use cable hanging system for rectangular ductwork supported by strut. The strut gripper comes in two sizes to be used with galvanized cable with diameters from 5/64” – 1/8”, providing working load limits ranging from 75 pounds up to 200 pounds per suspension point. (note: one piece of strut requires a gripper on each side – doubling the WLL shown below for that section). The strut gripper hanging system is easier and faster to install than traditional HVAC hangers and straps, saving time and labor costs. This strut gripper is designed to be used with upward facing strut (requiring a channel nut for installation) for secure support and allows the installer to make tool-free height adjustments and level ductwork quickly. The galvanized cable can be purchased in bulk spools or cut to length and supplied with a variety of end fittings to secure to structure.
