High Quality
Bar is slightly over ¼ inch, as advertised. Fits nice with less play than others. Business end has a small O-ring to keep dust and water out of locking mechanism. All chromed. Keys work smoothly, no break in.

A bit too long for me
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.

Looks good so far
Just received them so haven't used them yet but they seem to be good for the money and easy to use. Love the face that we can use one key for both of them. The quality seems good.

Bon produit
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.
