Model 2517-U was designed to fit 2 5/16'' UFP trailer couplers. The UFP trailer coupler is mostly found on larger boat trailers but in some cases trailer manufacturers offer UFP couplers as an upgrade. This style coupler can be found on other trailer types but it is not common practice. Our UFP trailer lock will work with or without surge brakes. Another great thing to love is our UFP coupler lock is made of 1/4 steel and domestic materials.
Designing the best coupler locks is not an easy task. We pride ourselves on producing a "glove like" fit coupler lock. Rest assured that Proven Industries trailer lock products will leave you with simply the best coupler lock on the market.
Trailer coupler lock model 2517-U may not fit all trailer couplers. Please look at trailer coupler lock index pictures below, if you do not see your trailer coupler picture please fill out the contact form to ensure you will get the correct trailer coupler lock. The UFP trailer lock will NOT allow you to secure both safety chains.
