Best Wraparound Trailer Coupler Lock with 5" Wide Lip

Updated 05/27/2020 | Published 05/22/2020

Question:

I like BX88351 or 3481213 that type of lock but I’m having a problem finding one of that type to fit over the flange of my trailer. I need at least 5” on inside of U shape to fit over flange 2 5/16. Can you give me a item # that will work?

The trailer coupler lock I recommend for a trailer coupler with large lip is the Master Lock Universal Trailer Coupler Lock part # 379DAT because the lock does not span the width of the coupler therefore the large lip is not nearly as much of an issue. The Blue Ox Trailer Coupler Lock part # BX88351 and options like it max out at around 4-3/4" wide.
