Here's a little more fun on this topic. I went to the local trailer place this morning and saw these on the shelf. The guy let me check one and they fit and close on my hitch! I stop at the camper so I can switch them out, and see that the ones that came on the camper are also 5/16", but they do not close. So, best thing to do is make sure you go somewhere that you can try one, don't go by size alone.

Here is even more fun.Does anyone know what the purpose of the little spring loaded clip is? I'll give you a hint,it is NOT to keep things from slipping out of the hook. Come on,all you iron workers,welders and riggers,step up!

Not a clue, I generally end up bending them to the point I remove them.

you can google anything...

OHSA 29 CFR Part 1926, Safety and Health Regulations for Construction, at 29 CFR §1926.753(d)(2)(ii) (in specified situations, "Hooks with self-closing safety latches or their equivalent shall be used to prevent components from slipping out of the hook...").

What is your explanation trbomax?

OK, times up. They are there so that the rigger/crane operator knows if the hook has been overloaded and deformed,as in opening up.If the hook opens up enough to allow the "retainer
"as it is sometimes called to open past the end of the hook or even move close to it,the hook has been overloaded and must be disgarded.This from my son who is a special project super at a nuc plant.He also has every certification for welding any metal with x-ray inspection, was a crane operator/rigger,all in union shops.

No that's not actually it. But if the hook does spread to that point yes it must be replaced. But the latch is not there for that reason.

You are mostly correct. But the latch is not required in all industry applications, nuclear and lifting personal yes. Construction yes they are required.
