Trailer Coupler Lock

Originally posted by henryv Don't get much for a nickel anymore! I thought of an idea too..I have a friend who's a welder. Spot weld a couple little pieces on the inside that would prevent the puck from moving so much.

So, since it was Friday, and the weather is nice.. I did some experimentation.
If I remove the outer collar, and mount the lock to it, I can wobble the lock quite a bit. But, that's because of free play with the narrower hasp point..



So, looking at it.. my $.05 fix. (it actually took $.10 to make this perfectly snug) in this setting. Again, for whatever reason, (manufacturing tolerance stacking I am sure) Ours is perfectly tight when assembled and mounted.







They could be held in place with a drop of super glue or silicone, heck, even duct tape..

Originally posted by GlueGuy A penny or two or three might be cheaper! Could also just put a slug from an electrical box in there too. Probably cheaper than a nickel.

I suppose, if you wanted to splurge, some combination of penny, nickle dime would get the very best snugness.. but who knows how much $$$ you might be out in the end...

I found the perfect solution. I had a couple of small round magnets that stick to the steel. Also sprayed the lock with some Blaster silicone lubricant and it works smoother.
