Which Locking Pin Will Fit The Adjustable Ball On The Curt Adjustable 2-Ball Mount # C99NR?

Question

Question:

Would locking hitch pins with 2 5/8inch spans also work well for those wanting to lock the adjustable part of the ball mount? Curious about both the fitment as well as potential for the presumed loads placed on them vs. the non-lockable pins that come with the mount. Thanks.

The Curt Adjustable 2-Ball Mount # C99NR uses Pins # C56NR which are 3/4" in diameter and have a usable length of 3-3/4". You will need the InfiniteRule Lock # IR36FR which is also 3/4" in diameter with a 3-7/8" span to lock the adjustable ball.
