Craftsman’s model 421165 Ratcheting Box End Wrench has has both an 11/16th end and a 7/8th end. That makes it perfect for the two standard sizes of ball lock posts! I’ve had a chance to give it a try and I think it’s amazing.
The ratcheting function speeds up post tightening and loosening. Having this wrench also means you’ve got one go-to wrench no matter what type of ball lock post you’re working with. The wrench is solidly built and has the Craftsman Guaranteed Forever Warranty.
Update: 9/2014. I’m still using the same wrench I got back in 2012 and it’s still working great.
