Seems stout and strong. Unlocking is easy - locking a bit tougher as you have to engage the locking side by pushing the two ends together, then turn lock by holding the locking end.My bigger issue is that there is gap between the ends when installed and the outside of the tongue itself, and I have a UFP surge brake tongue. This seems a place where a cutting tool or large hammer could facilitate cutting or braking of the lock. But you know what they say - "Locks keep honest people out".I gave it 4 stars because of more a me issue and ease of locking, than the construction workmanship which seems to be good.

This was for our pontoon boat trailer and it does a great job in securing it.

It fits nicely for my 2018 Yamaha 212X traiker coupler. One more security you must have. Easy to use and good value.

Bon produit et belle qualité. Nous avions déjà eu ce type de cadenas mais nous l'avons perdu. Nous sommes contents d'en avoir trouvé un identique. On s'en sert pour barrer notre trailer.

If you want to secure your grizzle charger from theft I believe this lock will do it.
