LD-149 Brass Cylinder Lock Core Set with Gift Box | Wholesale Supplier

The LD-149 Brass Cylinder Lock Core Set delivers professional-grade lock replacement and security upgrade solutions for homes, apartments, and commercial buildings. Each lock core is machined from solid brass bar stock for maximum durability and corrosion resistance, with a super B grade leaf tumbler mechanism that provides significantly higher anti-pick resistance compared to standard pin tumbler cylinders. The leaf tumbler design uses thin spring steel plates rather than pins, creating a complex key profile that is extremely difficult to duplicate without authorization. Each set includes 5 precision-cut brass keys with distinctive key bows for easy identification, allowing distribution among multiple household or office members. Cylinder lengths from 60mm to 90mm accommodate standard door thicknesses from 35mm to 55mm with various backset combinations. The premium gift box packaging with molded insert protects the cylinder and keys during transit while presenting an attractive retail-ready appearance. Whether replacing a worn cylinder, upgrading security after a move, performing apartment turnover rekeying, or installing new door locks, the LD-149 set provides professional security in a presentation-worthy package.
