If you are replacing a broken coupler on your trailer or installing a new one on a trailer you are building, CURT has dependable couplers you can trust to keep your tow load latched on tight. Selecting the right trailer hitch, ball mount and trailer ball to manage the weight of your trailer is not the only important aspect of towing; you also need a trailer that can stand up to the road ahead. That means equipping it with a coupler that is built to go the distance. As the name indicates, CURT A-frame couplers are meant to mount onto trailers with an A-shaped tongue. They are stronger than straight-tongue couplers and are especially common on RV trailers. This particular A-frame coupler features a easy-lock latch to be easy to operate. It is made from hardy steel construction and has a durable gloss black finish to protect from corrosion, wear and tear. This CURT A-frame easy-lock coupler features a gross trailer weight capacity of 10,000 lbs. and a tongue weight capacity of 1,500 lbs. It fits a 2-5/16" diameter trailer ball. All CURT couplers include a limited lifetime warranty and feature a lockable latch to give you peace of mind.
