These door lock assemblies are great. I do have to adjust the boly locations by reaming the holes to match up with my old lock assemblies, but lust minor adjustments for a perfect fit. 895260

This is the second set of trailer latches I have purchased recently. The latches from etrailer seem to be of better quality than the first set from another on-line company. Great product! 820996

Everything arrived on time & was exactly what we were looking for. Only thing that would've made this purchase even better is if bolts were included in the assembly. 819360

Parts arrived in great shape. Great packaging. The best thing was working with Odelia K. She is absolutely a great asset to your customer service department. I was looking for specific side door bar lock assembles to replace my current ones. I did not want to drill new (more) holes in my trailer. Odelia contacted your supplier and got the actual prints for the parts for me to review. By doing this I could verify that the bolt hole center spacing was exactly like the bars I was replacing. Odelia made great follow up calls back to me and was always friendly and very pleasant. In today's world with customer service almost non existent in a lot of company's she is a gem. 756729
