types of trailer couplers
CURT standard couplers, featuring our Posi-Lock latch, are the most common type of trailer coupler. With a mounting channel designed to fit onto a 3â trailer frame beam, the Posi-Lock coupler is easy to install.
Providing the highest weight capacity and the most flexibility in coupler design, CURT adjustable channel couplers are a unique option for your trailer. This type of coupler does not bolt onto a trailerâs frame the same way that a standard coupler does. It uses a pair of bolts to mount onto an adjustable eye channel to allow for easy height adjustment. The two attachment bolts also provide greater stability and less rattle.
