Will Trimax King Pin Lock Work on Grand Design Pin Box that Has Capture Plate

Published 09/08/2026

Question:

I have a short bed truck with super glide hitch and a grand design reflection 5th wheel with lippert 1621 and capture plate. Will the red Trimax king pin lock fit or do I need the yellow etrailer 5th wheel king pin lock? Thank you.

Hey Doug, yes the Trimax King Pin Lock part # TMX36RR that you referenced will work on your fifth wheel king pin setup that currently has a capture plate. This will work really well as a theft deterrent!
