LD-270 Brass Pin Tumbler Door Lock Cylinder 5-Pin 6-Pin | Wholesale Supplier

The LD-270 Brass Pin Tumbler Door Lock Cylinder is a precision security component designed for use in residential and commercial door locks, cabinet locks, cam locks, desk locks, and OEM lock manufacturing. The pin tumbler mechanism is the most widely used and time-tested lock cylinder design, providing reliable security through the interaction of spring-loaded driver pins and key pins that must align precisely at the shear line when the correct key is inserted, allowing the plug to rotate and operate the lock mechanism. The cylinder housing is manufactured from solid brass, providing excellent durability, corrosion resistance, and a professional appearance. Brass is the traditional material of choice for lock cylinders due to its machinability, dimensional stability, and resistance to environmental degradation. The internal pins are manufactured from nickel silver, a harder and more wear-resistant material than brass, ensuring long service life and consistent key operation even after thousands of insertions. The plug (the rotating core) is available in brass or hardened steel, with the hardened steel option providing drill resistance for enhanced security applications. The cylinder is available in 5-pin and 6-pin configurations. The 5-pin cylinder provides a good level of security for residential and general commercial applications, with 5 pin chambers providing a theoretical key differs of 1,000,000+ combinations. The 6-pin cylinder provides enhanced security for commercial and high-security applications, with 6 pin chambers providing a theoretical key differs of 10,000,000+ combinations. The cylinder is supplied with nickel silver keys that are cut to the specific pinning of the cylinder. The keys are available in a standard metal bow design or with a black plastic head for grip and identification. The cylinders can be configured as keyed alike (KA), where multiple cylinders operate with the same key, or keyed different (KD), where each cylinder has its own unique key. A master key system is also available, where cylinders can be operated by both individual keys and a master key. The cylinder is available in multiple finishes to match existing door hardware, including polished brass, satin nickel, chrome plated, antique brass, and matte black. The cylinder body is available in various diameters and lengths to fit different lock types, including 16mm for cam locks and cabinet locks, 20-25mm for standard door lock cylinders, and 30-35mm for commercial and mortise lock cylinders. Whether replacing worn door lock cylinders, rekeying residential locks, installing cabinet and furniture locks, manufacturing OEM lock assemblies, upgrading security systems, or building master key systems, the LD-270 pin tumbler lock cylinder provides reliable and precise security performance.
