For any and all types of trailers with electric trailer brakes, a CURT breakaway kit provides you with the equipment you need to be prepared. We offers three different complete breakaway systems to accommodate various trailer sizes and meet your specific towing needs. All of our breakaway kits are tested for your safety and meet DOT requirements for holding and breakaway situations. This replacement battery case for breakaway kits measures 5" wide, 3-1/4" high and 3-7/8" deep to fit a variety of breakaway batteries. It is constructed from durable polyethylene plastic to protect against the elements and features a lockable tab to accept a padlock and deter tampering and theft. This breakaway battery case is also equipped with a weldable metal bracket with a 3-1/8" inside diameter for convenient mounting on your trailer tongue or trailer jack post. Nobody hitches up a trailer expecting a breakaway, but that doesn't mean you should tow unprepared. Be ready for anything with a CURT breakaway kit.
