National Marker N830325 Door Hinge Oil Rubbed Bronze 3-pack

Product Description

The NATIONAL MARKER N830325 is a 3-pack of oil rubbed bronze door hinges sized at 3.5 inches by 0.625 inches radius. Built from heavy-gauge cold-rolled steel, these hinges deliver solid structural performance for interior door installations. The 5-knuckle design distributes load evenly across the hinge barrel, reducing wear over time. Countersunk screw holes allow fastener heads to sit flush with the leaf surface, and a nib detail on each hinge produces a clean, finished appearance at the door frame. Suitable for residential and light commercial door hanging applications.

These hinges are appropriate for standard interior door installations where a decorative oil rubbed bronze finish is specified. The 3.5-inch leaf height fits common interior door applications. The radius corner profile is a widely used style in residential new construction and remodel work. Each pack contains 3 hinges, providing enough hardware for a single door installation. Carpenters, finish contractors, and general tradespeople are the typical installers for this hardware.

Key Features

• Heavy-gauge cold-rolled steel construction for added strength and durability
• 5-knuckle hinge design for even load distribution along the barrel
• Countersunk screw holes for flush fastener seating

Compatibility

Designed as an OEM-style replacement or new-installation hinge for standard residential and light commercial interior doors requiring a 3.5-inch radius-corner hinge in an oil rubbed bronze finish.

Installation Notes

Installation is performed by carpenters or finish contractors using standard woodworking tools including a chisel, hammer, and screwdriver or drill driver. Power down any door-mounted electrical hardware such as electric strikes or access control devices before removing an existing hinge. Mortise the hinge leaf flush with the door edge and frame to ensure proper door swing and gap clearance. Follow applicable local building codes for door hardware requirements in commercial occupancies.
