What Size Door Latch Kit For 6x12 Enclosed Trailer With 4-1/2 Foot Tall Side Door?

Published 08/28/2025

Question:

I’ve got a 6x12 enclosed trailer with a side entry door that’s about 4-1/2 feet tall. Would the 45inch latch be a good fit for that?

Trevor, you’re right in the sweet spot - the 45inch latch # M343FR is designed for side or rear doors in that 4–5 foot range. It’ll give you plenty of bite top and bottom without sticking out past the frame.

Do you want it mainly for extra security or to help pull the door tight against the seals?

And for anyone else reading, what size latch ended up working best on your mid-size trailers?
