LD-321 Solid Brass 5-Pin Tumbler Keyed Padlock Standard & Long Shackle | Wholesale Supplier

The LD-321 solid brass keyed padlock series combines proven mechanical security with versatile sizing to serve a broad spectrum of locking applications from compact luggage locks to heavy-duty gate security. Available in body sizes ranging from 30mm to 70mm, each padlock is engineered around a precision brass 5-pin tumbler mechanism that delivers smooth key operation while resisting picking and bumping attempts. The solid brass body provides excellent corrosion resistance and structural integrity, making these padlocks suitable for both indoor and sheltered outdoor environments. Whether securing a school locker, a travel bag, a garden gate, or a workshop toolbox, the LD-321 series offers a body size and shackle configuration to match the requirement.

A defining feature of this series is the choice between standard and long shackle designs. The standard shackle variant features a clearance of 15 to 25mm, ideal for hasps, latches, and close-fitting locking points where a compact profile is preferred. The long shackle variant extends clearance to 35 to 50mm, accommodating thicker chains, gate bars, and awkwardly positioned locking hardware that a standard shackle cannot reach. In both configurations, the shackle is manufactured from hardened steel with a diameter of 5 to 10mm to resist cutting with bolt cutters and prying with bars. The brass 5-pin tumbler cylinder uses brass pins for consistent performance over thousands of locking cycles, and each padlock ships with brass keys so users retain convenient spare access.

For wholesale buyers and distributors, the LD-321 series supports extensive customization to align with regional market preferences and brand requirements. OEM logo engraving can be applied to both the lock body and keys, while keyed-alike and master key systems simplify fleet management across schools, facilities, and rental properties. Body finishes include polished brass, gold, chrome plating, and nickel plating, and custom shackle lengths can be produced to specification. Each padlock is supplied in a blister pack with cardboard backing for retail presentation, with 12 to 24 packs per carton for efficient logistics. With a minimum order quantity of 300 pieces, mixed orders across sizes and finishes supported, and a production lead time of 15 to 25 days, the LD-321 series is a dependable choice for importers seeking quality solid brass keyed padlocks at competitive wholesale pricing.
