National Marker N830434 Bi-fold Door Hinge Oil Rubbed Bronze

Product Description

The NATIONAL MARKER N830434 is a surface-mount, non-mortise bi-fold door hinge finished in oil rubbed bronze. It features a non-removable, tight, non-rising pin that stays secure through repeated operation. The hinge mounts directly to the door and frame surface, so no mortising or chiseling is required. This is a catalog model V530, sized at 3 inches. It is suited for residential interior applications and is typically installed by finish carpenters, general contractors, or experienced DIYers handling door hardware replacement or new installation.

This hinge is designed exclusively for bi-fold doors with a minimum thickness of 1 inch. The surface-mount design makes it a practical choice for retrofit projects where cutting mortises into existing door frames is not feasible. The oil rubbed bronze finish suits period and transitional interior styles. It is sold individually and ships in pack quantity.

Compatibility

Designed as a surface-mount replacement or new-installation hinge for bi-fold doors with a minimum thickness of 1 inch. No specific compatible door or frame model numbers were provided in the product data.

Installation Notes

Turn off any power to motorized or automated door systems before beginning work. The surface-mount design allows fastening directly to the door face and frame without routing or chiseling. Use the appropriate screw size for the door material and ensure fasteners are driven flush to avoid interference with door travel. Verify door alignment and smooth bi-fold operation after installation before returning the door to service.
