Good lock for the lock pin of my trailer. Long enough for different applications.

A great substitute hitch bolt and lock for the Thule bike rack. Itnstead of buying a Thule hitch pin for 70$, I bought this for so much less and it works great!

I keep it installed going down the road to. anything that can go wrong will. piece of mind nothing bad will happen. the key cover is nice so water can't get in to damage the device.

Perfect tongue lock for the trailer to discourage theft, works great to lock the trailer on the ball while in transit. as well.

Use it to secure my boat trailer. Easy to lock and remove with the key. No problem

This thing works perfectly. Makes me feel safe when leaving my trailer hooked up somewhere or when it is parked by itself

I had a hard time finding a pin that was small enough to go through the receiver pin hole, this worked well, seems secure.

I purchased others ( hoes shoe style) and they skimped on the rod length. When closed the locking rod barely made contact with end. Quick pry with a screw driver popped it off. This fits securely.

The lock is good for trailer hitch with small hole. It is good because it is adjustable for different lengths, however it wouldn’t take much force to be able to break it in the area where the shaft is thinner

This one is simple to use and hasn’t let me down yet and now I bought two of them.
