I am looking for a source of buckles/clamps capable of taking my 2 inch wide tie-down webbing. Somebody walked off with my old tie-downs while I was on the water for 40 minutes, having inadvertantly left them on the ground behind my car at the launching ramp. What I have in mind are the spring-loaded clamps with a saw-tooth gripping edge. I have seen narrower ones at the fabric store, but wish to upgrade while I'm at it.
