Model 2517-B was designed to fit BullDog style trailer couplers with a trigger latch. This model will also secure the trigger latch when installed. The outer shield covers the trigger latch so it can not be opened. This style trailer coupler is usually found on heavy duty trailers such as those used in commercial applications and heavier weight-rated trailer applications. In most cases, Bulldog style trailer couplers will be found on commercial trailers, but in some cases trailer manufacturers offer Bulldog couplers on non-commercial trailers as an upgrade.
This model is specifically for BullDog trigger latch couplers that are square on top. BullDog also makes a similar model that has a dome on top that this model will not fit.
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. This model will not secure any size safety chains.
