The SureClose® SM hinge was designed for large industrial-style gates, such as found on commercial and heavy residential gates, plus estate gates and gates around factories, schools, access control areas and driveways that don’t require self-closure. The SM model features extra-large hinge pins and dual thrust bearings designed for high loads. Save money when SM is used as the bottom, load-bearing hinge along with a SureClose® 57 or SureClose® 108 closer. All SureClose® hinges and closers come packaged with the gate mounting bracket included. Post mounting brackets sold separately.
