4-Way Pressure Release Clamp – Wood Panel Corner Clamping System Woodworking Bracket Set

I put these on Unistrut, and they work as good as the ones you pay $100 for. You will need screws and t-bolts that work with Unistrut but they are cheap. Unistrut come in 10ft lengths so you can cut it to the length you need.

I open the box it came in and removed it and looked at the way it was made. It was so bad that I knew it would not be able to put pressure on the wood with out failing.

Husband is pleased with the way these clamps operate. The clamps equally provide pressure from all four directions to decrease the chance of the glued wood buckling. They are well made, of metal and plastic, and seem heavy duty and sturdy. Instructions would have been very helpful to have.

Beautiful clamp (Period). If you are gluing up side grain this clamp can save some time (planing and sanding) and a little material, but if you're gluing up end grain this clamp is SuPeR HanDy. I make alot of end grain cutting boards; end grain is super hard. It probably takes 20 times longer to sand end grain than it does to sand side grain - Not kiddin'. This clamp ensures that my glue up leaves my boards as level as possible. That equates to avoiding some if not all of the planing where, with every pass through the planer, there is a danger of getting some chip out. It can also mean less passes through the drum sander, where it's always possible to get burn marks that end up exponentially increasing sanding time.I can get the same results at glue up using regular clamps and scrap boards – but it requires careful planning and more time. Time is a valuable commodity at glue up, and if that Murphy guy shows up things can get screwed up. Consequently, this 4-Way Pressure Clamp has become a valuable tool in my end grain cutting board glue ups.I vaguely remember there being a schematic in the box to aid in assembly – but can't find the box to confirm. Regardless, a schematic isn't necesssary – look at the picture and put it together – it's an intuitive assembly.7 Super Novas for The Nagu 4-Way Pressure Clamp~ Thanks for Reading – Have an Incredible Life! ~
