Here we have a bucket of clamps to make a frame for boat covers using ¾ Conduit. They clamp to boat rails to make a complete frame for winter covers. I used them to make a frame for a 39 foot boat for years when storing outside. I was able to work on boat year around inside the tarp without any issues. Takes a little work the first time to cut and bend the conduit but once done and marked comes apart and stores easily and goes up quick in the fall. Clamps only no conduit or tarp included. Can be picked up or buyer pays shipping about 40 pounds
