## Description

Master Lock Trailer Lock, Stainless Steel Adjustable Coupler Latch Lock, 2847DAT

Review: Muy práctico y resistente a la interperie, este candado lo adquirí para reponer uno va idéntico que use durante más de 10 años el cual nunca se trabó y siempre funcionó bien el cual se me me extravió y me peso, probé otros dos modelos distintos de otras marcas pero este es para mi el más práctico y seguro de uso
Review: I was looking for a lock that can lock my trailer, I asked a question if the lock is 6mm, after waiting for one week, no one answered, so I have to take a leap & buy it, unfortunately its 7mm plus, had to return it. I had added two pictures, with 2x measurements from different places, both have different readings, my calliper is lab calibrated by a calibration company, so its 100% correct. The whole specification includes every thing, but the most crucial part was missing, picture attached for those who are looking for such info, it would have been appreciated, if seller had responded to the question.
