    Great Product! I just Purchased One of these and the Added Security this Added the First Time I Used it made it Worth it! The Little Pin that came on my Trailer didnt Lock on and I was always Afraid that it would Rattle Out on Long Trips. This Took Away All of my Doubts. Great to have them All Keyed Alike too! Thanks, Durasafe…

    I bought this along with locks for my three Helix 12’s. They are all keyed alike making things easier. Both products are just as promised

    Excellent quality fast shipping, The ultrex trolling motor lock is easy to install and will make it difficult to steal, the coupler lock is made well and the keys work well for both locks.
