Model 2178-U was designed to fit 2'' UPF trailer couplers. The UFP trailer coupler is mostly found on boat trailers. UFP style couplers will mostly be found on boat trailers, but in some cases trailer manufacturers offer UFP couplers as an upgrade. Our UFP trailer lock will work with or without surge brakes, look below and you can see both styles in the coupler index. Another great thing to love is our UFP coupler lock is made of 1/4 steel and domestic materials. Safety chains can also be secured inside the UFP trailer lock.
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. Some style of safety chains you will not be able to secure inside this style of coupler lock.
