So, everyone should have a lock at this location (circled in red), both while hitched or unhitched.

I'm told that 1/4" diameter pin fits this hole. You may have a bolt there currently. (the previous thread: http://www.airforums.com/forums/f464...ase-65983.html )

I still need to find out, if its SPAN is narrower or wider than 5/8", so I'll know which exact lock to order.

LIFELONG locks ( LifeLong Locks - The Strongest, Most Theft-Proof Trailer Locks You Can Buy ); they are nice, stainless with harder-to-beat proprietary tumbler.

Both are 1/4" diameter, one is 5/8" span, and other is 1" span.

Fitting the lock with narrowest span can be a big difference on its effectiveness for deterring theives to use bolt cutters and saws, or perhaps even power tools.

I'm hoping some of you on this forum may be at your trailer now and can spare 2 minutes and share the info.

Thanks in advance, sincerely.

Just for you I went out and measured. With a micrometer.

The widest part of the stamped coupler latch, which is tapered, in the vicinity of the hole intended for the shackle of a padlock, is 0.539" on my traylah.

With micrometer! That is more than I expected. Domo Arigato :-)

So, 5/8" (=0.625") span should fit.

Ok, this is what should be ordered then, and I'm ordering it now.

PSA: EVERYONE SHOULD ORDER THIS...
5/8" Stainless Steel Coupler Latch Lock

I will report the actual fitment in a few weeks when I get to my trailer.

Again, thank you, Jammer-san!

Hi, I just went out side and took two pictures for you, using what I call a mechanic's quick micrometer. Note: this part is not what I would call a precision part, and the wrench, [mechanic's quick mic] fit loosely.
