Master Lock Co 6271 Shackleless Padlock Hockey Puck

Product Description

The MASTER LOCK CO 6271 is a shackleless padlock designed for high-security applications where a traditional shackle would present a cutting or prying vulnerability. Built in a hockey puck style, the lock body measures 2.875 inches and is constructed from die cast material for rigid, impact-resistant performance. The six-pin re-keyable cylinder adds flexibility for facilities or fleets that need to rekey locks without full replacement. This lock is suited for licensed security professionals, fleet managers, and trade contractors who specify commercial-grade hardware on freight, cargo, or automotive assets.

The 6271 is commonly specified for freight line security, trailer door hasp applications, and automotive storage enclosures where the absence of an exposed shackle prevents bolt cutter or saw attacks. The shackleless body sits flush against the hasp, eliminating the gap that standard padlocks leave exposed. It is also used in commercial facility access control, tool storage, and high-value cargo transport scenarios. The six-pin cylinder configuration provides elevated pick resistance compared to standard four- or five-pin designs.

Compatibility

Designed as an OEM-style replacement or direct-specification shackleless padlock for standard hasp and puck-lock mounting applications in freight, automotive, and commercial security installations.

Installation Notes

Installation is typically performed by a licensed locksmith, security contractor, or qualified facilities technician. Ensure the hasp or door receiver is rated for a shackleless puck-style lock before installation, as mounting geometry differs from standard padlock hasps. Verify that the mounting surface and hasp hardware are free of corrosion or deformation before securing the lock body. Rekey operations should follow the manufacturer's cylinder procedure using the appropriate rekey kit.
