Today we'll be demonstrating the Diversi Tech Universal trailer coupler lock for an inch and 7/8, two inch and two and 5/16 inch coupler, part number DT25013. Now this lock will let me protect just about any trailer from theft. It uses a unique ball and shackle to fit a variety of coupler sizes and styles. Today we'll be installing it on a Bulldog trailer coupler. It's made out of a hardened chrome plated shackle and nickel plated housing. It has an ANI drill pin discouraging attempts to drill out the lock.
Now with our Bulldog coupler open we'll use one of the four keys, included with the Diversi Tech Lock, to unlock the lock and remove the shackle. We'll then place it up into the coupler and bring the shackle down and lock it into place. There you have it our trailer is locked up. That'll complete the demonstration of the Diversi Tech Universal trailer coupler lock for an inch and 7/8, two inch and two and 5/16 inch coupler, part number DT25013.
