Why Choose ICS Trailers
Gate pockets can look similar, but this version needs the 4″ size and 62mm inside profile matched correctly. It also suits 4″ RSJ applications. If you are replacing an existing pocket, send ICS Trailers the old part photos and key measurements. We can then help narrow down the fit before you order.
- Compare the pocket opening and surrounding side-gate hardware during the repair.
- Check the 5″ variant separately if the existing pocket is larger.
