Product Description

The NATIONAL MARKER N830197 is a round-corner residential door hinge finished in oil rubbed bronze. It measures 3.5 inches in height with a 0.625-inch corner radius, making it a standard fit for interior door applications. The hinge features a removable pin that simplifies installation and removal without specialized tools. Mounting screws are included. Constructed from steel, this hinge delivers the structural integrity needed for everyday residential door operation. Licensed contractors and experienced DIYers alike install this type of hardware as part of interior door rough-in and finish work.

This hinge is designed for interior residential door installations where a round-corner mortise profile is required. The oil rubbed bronze finish suits common interior design schemes in residential construction and renovation. It is sold individually, making it practical for single-hinge replacements or full door-hanging projects where specific quantities are needed. The 5/8-inch radius corner matches standard router templates used in residential door prep.

Installation Notes

Installation is typically performed by a finish carpenter, general contractor, or experienced DIYer during interior door hanging or replacement. Power down any associated door hardware before servicing electric strike or access control components. Use a chisel or router with a matching radius template to prepare the mortise to the correct depth before seating the hinge leaf. Ensure both door and frame leaves are flush-mounted to prevent binding.
