Description

Brand: PRIME LINE PRODUCTS
Manufacturer Part Number: N 7273

The PRIME LINE PRODUCTS N 7273 is a two-pack of satin nickel bi-fold door hinges constructed from steel. These hinges feature a non-mortise design, meaning they mount directly to the door’s edges without requiring chiseling or mortising. That makes installation faster and reduces the risk of damaging the door or frame. The satin nickel finish provides a clean, neutral appearance suited to standard interior applications. This product is sold in a two-pack and is carded for retail-style distribution, though it is equally appropriate for trade stocking and service work.

These bi-fold door hinges are used on bi-fold doors installed by a variety of wardrobe manufacturers. They are well suited to residential interior applications including closets, laundry rooms, and utility spaces where bi-fold door hardware needs replacement or upgrade. The non-mortise edge-mount design is compatible with standard bi-fold door configurations and does not require specialized tooling beyond a drill and appropriate bit.

Installation Notes

Installation is performed by carpenters, general contractors, or experienced DIYers working on interior door hardware. Before installing, drill pilot holes using a 3/32-inch bit to avoid splitting the door material when driving fasteners. No mortising or chiseling is required due to the non-mortise edge-mount design. Ensure the door is fully supported and stable before securing hardware.
