Pro Series Weather Tough padlock

This laminated steel padlock uses an interchangeable SFIC core so facilities can re-key or swap cylinders without replacing the whole unit. It suits maintenance teams, property managers and anyone who needs a single key system across multiple doors.

Boron shackle and six-pin cylinder

The 5/16 in boron shackle resists cutting and sawing while the six-pin cylinder provides standard pick resistance for perimeter gates, storage units and utility enclosures. It is not rated for high-security applications that demand drill-resistant cores or restricted keyways.

Interchangeable core accepts any OEM SFIC

The lock ships ready for an SFIC cylinder so existing master-key hierarchies extend to this padlock without new keys. No control key registration is required, but the core itself is not included and must be sourced separately.

Questions about this item

Will the 5/16 in boron shackle fit the existing hasp on my shed?

The shackle diameter is 5/16 in with a 1 1/8 in clearance height and 7/8 in width; measure your hasp hole and internal gap to confirm fit.

How do I verify the 6-pin cylinder operates smoothly after installation?

Insert the key and turn; the cylinder should rotate freely without binding and the shackle should release cleanly when the key reaches the open position.

Does the package include a control key for the interchangeable core or must I order one separately?

The lock accepts any OEM SFIC core; a control key is only needed if you purchase a core that requires one, and registration is not required.
