Our original Brewhouse came with clamps from Sani-fit and I've been hoping someone would replicate the clamp design ever since. They have a pretty deep groove a lightweight double hinge, which makes them ideal for sucking together the fittings and holding them tight by hand while you're flipping the catch over and tightening it down. Almost every other clamp I've used is an exercise in frustration in comparison. You can't hold them tight enough with one hand to keep the clamp engaged while you're locking them if there isn't a nice stress free alignment of hose/pipe etc. If there's a manufacturer out there whose interested in the design, I'd be happy to send them one. They were also fairly light weight in comparison to a lot of the others I've seen (think economical use of Stainless Steel) but I've never had one fail in over 20 year of service.
