The HAGER HINGE 337C is a template hinge shim designed to fine-tune door hinge alignment during installation and adjustment. Measuring 5 inches in length and 1.5 inches in width at 0.028 gauge thickness, this shim fits behind standard template hinges to correct minor gap inconsistencies and achieve proper door leaf positioning. The prime coat finish makes it ready for field painting to match the surrounding hardware finish. Door installers and finish carpenters reach for shims like this when correcting hinge mortise depth or compensating for frame irregularities on commercial and residential door assemblies.
The 337C shim is suited for use in both new construction and retrofit applications where template hinges are specified. It is commonly installed on hollow metal frames, wood frames, and steel door assemblies in commercial buildings, schools, healthcare facilities, and multifamily residential projects. The shim is sold individually, making it practical for targeted repairs or small-volume adjustments without the need to purchase a full case.
Designed as an OEM-style replacement shim for use with standard template hinges on commercial and residential door assemblies.
Installation is typically performed by door hardware installers or finish carpenters working to ANSI and BHMA template hinge standards. Before adjusting or shimming hinges on an active door assembly, ensure the door is secured in an open position and any closers or hold-open devices are disengaged. Place the shim between the hinge leaf and the mortise surface to achieve the desired alignment. Do not stack multiple shims beyond what is needed to correct the gap, as excessive shimming can compromise fastener engagement depth.
