Overview

The P-COOV-1031-P-N is a heavy-duty mechanical overrun coupling assembly designed for use on Brian James trailers.

The complete HU12 unit carries AL-KO part number 185004115.

AL-KO & Bradley Doublelock — What You Need to Know

Bradley Doublelock was a well-established manufacturer of trailer coupling systems. Following AL-KO's acquisition of Bradley Doublelock, the product range was integrated into the AL-KO portfolio. If you have previously sourced this part as a Bradley component, the AL-KO equivalent is a direct replacement. Replacement units and spare components — including the AK351 coupling head — are now supplied under AL-KO branding and part numbers.
