Easy-to-use side clamp attached to a 5 foot-long bungee cord. Works with HQ Studio Frame or HQ24 Fusion Frame, which have an opening in the sidearms designed to hold the bungee cord. Clamps provide needed tension to the quilt. Listed price is for a single clamp. We recommend using at least two sets of clamps, one set on each side of the quilt for extra support.
