Poor design:
1) The 1/2" pipe clamp has very thin and weak springs pushing the clutch plates; without the pipe, plates/spring would easily fall out.
2) The idea of eliminating the need for threaded pipe is nice but poorly executed; the clutch plates do not hold the pipe firmly thus allowing the clamp's upper part to spin as you rotate the handle
3) The plastic clampshell cover is very flimsy which broke during shipment allowing the clutch plates & springs from all 4 of my clamps to fall out!
The Quick-Grip Pipe Clamps Innovative clutch system eliminates the need for threaded pipe. Its larger feet offer more stability and clearance between handle and worktop. Provides larger, more ergonomic handle offers easier clamping with reduced hand fatigue. Its larger clutch plates allow for easier release and increased durability and dependability.
