The SMACNA Testing and Research Institute verified Looping Gripper from Griplock Systems is an easy-to-use cable hanging system for spiral ductwork. The looping gripper comes in three sizes to be used with galvanized cable with diameters from 1/16” – 1/8”, providing working load limits ranging from 75 pounds up to 250 pounds. The looping gripper hanging system is easier and faster to install than traditional HVAC hangers and straps, saving time and labor costs. It is designed to create a loop around spiral duct for secure support and allow 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.
