National Mfg N208-835 3x3 Galvanized Loose Pin Hinge 5-pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N208-835 is a 3 inches x 3 inches galvanized loose pin hinge designed for full mortise door installations. Manufactured from cold rolled steel with a galvanized finish, this 5-knuckle hinge is swaged for precise mortise fitment. The loose pin design allows doors to be removed from the frame without unbolting the hinge leaves, which saves time during installation and service work. Each hinge carries a safe working load of 50 pounds. This package contains 5 hinges. Licensed carpenters, finish contractors, and door installers are the primary users of this hardware.

This hinge is suited for residential and light commercial door applications where a full mortise installation is required. The galvanized finish provides corrosion resistance in moderately humid environments such as utility rooms, basements, and covered exterior doorways. The loose pin feature is especially practical in high-traffic commercial settings where doors may need to be removed periodically for access or equipment movement. Five hinges per package suits single-door and multi-door job quantities.

Installation Notes

Installation is typically performed by carpenters or finish contractors using standard mortise chisels, a drill, and a screwdriver or impact driver. Remove the door from the opening before routing mortises to ensure accurate placement of both the door leaf and the frame leaf. Always confirm that the combined hinge count and working load rating supports the weight of the door before installation. The loose pin should be fully seated and tapped flush before hanging the door.
