Question

Question:

The Trimax TMX56rr I bought does not fit my New Morryde RPB72-FD pin box or the Rota flex that came whit my 2024 Brinkley Z3100. I did not purchase the Trimax from you. The Trimax fit my old Airride Pin. Can you give me an idea which lock to use

Since the Trimax # TMX56RR did not fit, I recommend taking a look at the etrailer 5th Wheel King Pin Lock # e98896. I like this lock because it is designed to be universal, and will fit virtually any pin box with a standard kingpin. The collar of the lock is 1-1/2" tall, which allows for a secure fit, even on Pin boxes like the Morryde RPB72-FD where space may be limited. These locks can also be keyed alike, if you want to order multiple locks that use the same key.
