I'm looking for a source for high-load cam buckles for use on 1" nylon jackline webbing. Preferably stainless steel. I want something with a minimum 2500lb breaking strength. Ancra seems to be the manufacturer of 90% of the cam buckles on the market, but I'm having a hell of a time finding good descriptions of the items they make and sources for buying just a couple of the buckles. I must've looked at 5 dozen web sites. If anyone can point be in the right direction, I'd be very grateful.

John re: strapworks
Been there, looked at that. They are cast zinc (corrosion here we come!!) and not strong enough. Ancra makes other versions with higher strength ratings. At least, some of the other sources for tiedown straps claim that to be the case. Thanks, though... the search continues. ------------ I found one with 2200lb BS, but it's still zinc. They have SS ones rated at 1800lb. (See link.) Want stronger than that though. Safety equipment BS should be rated at 15X the working load.

Steve: Length adjustment
Both ends of the jackline will have a locking carabiner (or spring clip) and attach to folding padeyes on the deck. I can estimate the webbing length pretty closely and sew loops in both the ends for the 'biners/clips, but over time the nylon webbing will stretch. I want to be able to adjust the length of the webbing and tighten it down. I don't want the jacklines to be laying real loose on the deck -- they'll be a stumbling hazard. Thus the cam buckles. One end of the line will have a sewn loop for the bow 'biner/clip. For the stern end, the buckle will be stitched to the line a couple of feet from the end. Then the free end will loop around the stern 'biner/clip and go back through the buckle. Now I can tighten it down...

Carabiner on one end.
Doug: If you put the carabiner on one end and then you can tie the other end off on your docking cleats (bow or stern). When this webbing gets wet (as you probably know) it tends to get loose. You can just tighten it up as required. This is how they did it on the Santa Cruz 52 that we came home from Hawaii on 2 years ago.

I too need some right now and have looked all over for these things. The best I could find come from "Sea Sure" in the UK. They have sliding bar buckles for 1" jackstay webbing and these are rated at 3500 lbs. Their catalogue is on their website and they are an international company. As I need fittings to attach the webbing to the deck simple buckles will not do. I have a Hunter 376 which does not have an aluminium toerail so there is nothing to attach jackstays to. So I spent all of Wednesday and Thursday hand sawing and filing 14 gauge (.08") stainless steel sheet and have made myself two fine sliding bar buckles. It was the hottest day of the year and I really cannot recommend this activity. These buckles will bolt inside the anchor locker and the webbing will lead out through the opening - fortunately the locker lid is a bad fit. If you feel inclined to make your own I can e-mail you my drawing. Good luck with your search.
