I invented and designed what I think is the best modular bar clamp ever made. It combines the best features from existing clamp designs. The clamps are fully modular and extremely affordable, great for woodworking or any DIY projects. They have a clamping capacity of up to 1000 lbs, and cost as little as 5 dollars per clamp.
I hope to bring these clamps to market. But for now I got DIY kits available.
