I bought this for a new trailer and found it to be very sturdy and solid in its construction and gives me confidence that the trailer will be safe. It is easy to put on and take off. I would recommend this lock.

I am happy with the trailer lock. I had problems at first because I put it on too tight and could not get the lock to unlock. I emailed support after business hours and had a super helpful reply within minutes.
