I have been looking for a specific kind of suspension buckle for a long time with no luck. Now I'm wondering how difficult it would be to DIY something. The form I have in mind is basically the JRB Tri-Glides with an added triangle at the end. The finished buckle would be a bit like the Elephant Trunks, but without the 3rd slot and the open "trunk". The whoopie slings would be permanently spliced into the triangle (the adjustable end).
If a buckle like that already exists, I'd be happy to hear. I prefer to buy this type of equipment rather than DIY.
