Mag-Mate Kant Twist Clamp
We love these clamps because they’re lighter and stronger than c-clamps of similar size. Their gripping surfaces often come with notches cut into them, as well, so they're especially great for clamping round bar to flat surfaces. We enjoy keeping these around in a handful of sizes and think you will too. They're more pricey than c-clamps, but are more flexible in their use and won’t “walk” off center as they’re tightened, either!
