YF812 is part of the Yanfeng Heavy-Duty Lever Locks collection. Heavy-duty lever locksets for entrance and storeroom duty, on a reinforced chassis rated to ANSI/BHMA A156.2 Series 4000 Grade 2. Twenty lever and knob designs on one platform.

Specification

Every model in this collection shares one finish system, one function-code system and one packing standard, so a project can mix ranges without translating between them. Build the order code left to right: YF812 / function / finish / handing — anything left unstated is supplied in the standard configuration.

  • ANSI/BHMA A156.2 Grade 2 chassis
  • Fits doors up to 50 mm
  • Twenty designs on one platform

Ordering

Keyed different is standard. Keyed alike and master key systems are available on request in all four keyway profiles (Kwikset, Weiser, Yale, Schlage). Minimum order is one carton per model and finish; mixed cartons by arrangement.

OEM and ODM

Heavy-Duty Lever Locks can be supplied under your own brand: custom packaging and inserts, laser-marked logo, private keyway and a dedicated model number. Send a sample or a drawing and we will come back with tooling cost, unit price and a sampling schedule.
