Grimmer got a reaction from HumanPerformance in Captains of Crush Grippers
Thanks for all the info guys, that's great!
The COC #3 approx poundage is 280lb (127kg).
Wow, no one in NZ officially certified? I know what you are saying. It is one thing to close a gripper but doing it officially with a Credit Card Close is another.
Hopefully I do it soon. It's my goal for this year.
