No more bicycle clips slipping off the quilt roll and rolling all around the floor. The teeth of JAWS will hold your quilt roll firmly. JAWS is made of Lexan® and is flexible, just open and twist to put on the quilt roll. The two sizes of JAWS will be particularly helpful as one side of the quilt roll gets larger and the other side smaller. One quilt will require at least 8 clips; each package contains four clips.
