Import Door Handle-4-72 — Buy in Bulk from Supplier in China

The Door Handle-4-72 is a robust door hardware component designed for high-traffic environments, constructed from corrosion-resistant metal alloys with a focus on mechanical durability. It features a standard backset of 64 mm and a spindle diameter of 8 mm, compatible with most mortise lock systems. The handle measures 120 mm in length and 45 mm in width, with a projection of 55 mm from the door surface, ensuring ergonomic access without snagging on clothing or furniture.

The base material is typically zinc alloy die-cast with a protective electroplated finish, common in commercial-grade hardware. Surface finishes include satin nickel, chrome, and matte black, each tested for salt spray resistance per ASTM B117 standards. These finishes are not painted but deposited through electrolytic processes, offering greater longevity than powder coatings. The internal mechanism uses ball bearings for smooth operation, a standard feature in industrial door handles intended for continuous use.

This handle is widely specified for hotels, office complexes, and institutional buildings where security and frequent usage are priorities. Buyers include facility managers, architectural contractors, and bulk distributors serving the construction sector. Trade terms are typically FOB Ningbo or CIF destination port, with packaging in bulk cartons of 50 units per box. Minimum order quantities are not stated but are generally negotiable based on shipment volume and packaging requirements.
