This kit is built for owners who need a precise, heavy-duty solution for 2-5\/16\" fixed couplers on A-frame trailers. It combines a saw- and pry-resistant coupler lock with a complementary tongue lock, both finished in powder coat to withstand rain, salt, and UV exposure for long-term outdoor use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit fit my trailer's coupler?\u003c\/h3\u003e\n\u003cp\u003eThe kit is engineered for select 50×50mm and 50×60mm couplers and standard 2-5\/16\" A-frame trailer couplers.
