Mag-MateK045TD Kant-Twist Clamp with T-Handle, Deep Throat Welding and Fabricating Clamp, Multi-Purpose Lever Clamp, Cantilever Arm Clamps For Secure Hold, 4.5” Opening Capacity

Little bit pricey for one clamp but it definitely has its use. Would not use for super high clamp loads like over 100 pounds per clamp. Does not feel to be cheap and the material good quality but the design does not lend itself to super high clamping forces.

Solid clamping, no twist, and low-profile. Or at least differently-profiled, in any case they fit in some tight spots that my normal c-clamps don’t

They're awesome, no c-clamp twist, great holding power, non-marring.

Must have for welding, They work great for a third hand to get good welds.

The clamp is great for applying lots of pressure, if needed.

I used these style clamps years ago as a machinist and these are just as good. These are professional grade tools.

Greatest clamp for attaching work to precision 90 plates. Don't twist like C-clamps.

Life savers. Non marring copper pads save me so much time working on cosmetic parts.
