I stumbled across these on Facebook while looking for something really secure but not crazy expensive.
Called the maker to make sure which would fit my trailer and he was very helpful. Decided to take a chance and order one.
Extremely happy with it. It is beautifully made, solid THICK steel and nicely welded and finished.
It would take hours to cut through it and a crowbar is not gonna work. Seems to me to be at least the equal of, if not better than the two “big name” similar locks and at a much more attractive price.
It comes with a padlock that is better than average, but not the highest spec (which the maker freely discusses) and he suggests that if you are really worried about it its easy to order the most bulletproof one and change it out.
IMHO, it si more than enough to make the crook move down the row, and they are unlikely to want to lay on the ground and try to drill the lock out after the steel defeats them.
By far the best value I found - highly recommended.
