I have "Leader Grips" - similar product. They work well. If the "grip" is too tight, just buy a length of dowelling a little bigger diameter and put the grip on it for a while - it will stretch it slightly as if you had used it awhile and make it easier to put into place. I don't use pins anymore to attach the quilt components to the frame. I still use them at times to anchor fabric where I want it prior to basting etc.
