Bungee Grabbers™ are compatible with HQ Gallery 2™, HQ Studio™ 1 & 2 and HQ Fusion™ Frames. Special cam cleats lock the bungee cords in place after a quilt sandwich is secured in the side clamps. The original factory-installed bungee clamp will need to be removed from the Side Arm assembly before installing the Bungee Grabbers.
