Easy-to-use set of two side clamps attached to a 6-foot bungee cord. Compatible with HQ Studio, HQ Studio2, or HQ Studio3 frames, HQ Gallery/Gallery2 Frame, or HQ Fusion Frame, which have an opening in the sidearms designed to hold the cord. Clamps provide needed tension to the quilt. We recommend using at least two clamps, one on each side of the quilt for extra support.
