Husky straight couplers are perfect for safe towing of 1-7/8 inch and 2 inch trailers. Husky straight couplers are built to the highest industry standards, tested and certified to meet VESC Reg.

For increased safety, each Husky straight coupler includes a safety pin as an additional means of securing the ball clamp in a locked position (safety pin is required to be used at all times) and a safety chain to eliminate loss of the safety pin. The quick release assembly allows for fast and safe locking and unlocking of the ball clamp for convenient hook-up and disconnect. Sleeve packaged.
