Master Lock Co 15SSKADLJHC Laminated Padlock 6-pack

Product Description

The MASTER LOCK CO 15SSKADLJHC is a stainless steel laminated padlock built for demanding outdoor and industrial applications. The body is constructed of laminated stainless steel layers, providing strong resistance to cutting, prying, and weather exposure. The shackle measures 2.5 inches in length with a 3/8 inch diameter, also in stainless steel, for added corrosion resistance in wet or coastal environments. This padlock ships in a keyed-alike set of six units, meaning all six locks operate on the same key — a practical choice for facilities, job sites, or fleet operations where a single key must open multiple points of access. Licensed tradespeople and facility managers are the primary installers.

This padlock is suited for gate locks, equipment enclosures, utility panels, storage units, and outdoor service access points in both residential and commercial settings. The stainless steel construction makes it appropriate for pool equipment areas, rooftop HVAC equipment, exterior electrical enclosures, and marine-adjacent environments where standard steel hardware would corrode prematurely. The keyed-alike-in-sixes configuration reduces key count for technicians managing multiple secured access points on a single site.

Compatibility

Uses key blank K15BOX or Ilco M10-TV True Value 137-588. Designed as an OEM-style replacement or direct addition for applications requiring stainless steel laminated padlocks with a 2.5 inch shackle.

Installation Notes

Installation requires no tools beyond the key provided. Before securing electrical enclosures or utility panels, confirm that power has been isolated and lockout/tagout (LOTO) procedures are followed per applicable OSHA and NEC guidelines. Do not force the shackle into an undersized hasp — verify hasp clearance matches the 3/8 inch shackle diameter before installation. Periodic lubrication of the keyway with a dry lubricant will maintain smooth operation in high-humidity or saltwater-adjacent environments.
