Master Lock Co 3SSTHC Laminated Padlock 1.5 in Keyed Alike 2PK

Product Description

The MASTER LOCK CO 3SSTHC is a laminated steel padlock sold in a 2-pack configuration, designed for applications where weather exposure and cut resistance are primary concerns. The body is constructed from laminated steel with a protective weather coating, and the shackle is stainless steel for superior resistance to corrosion and cutting attempts. The shackle measures 3/4 inches in length with a 9/32-inch diameter. Both locks in the pack are keyed alike, making this a practical choice for facilities, job sites, or equipment where a single key must operate multiple locks.

This padlock is suited for outdoor and semi-outdoor use in trade environments where hardware is exposed to moisture, chemicals, or temperature swings. Common applications include securing electrical panels, HVAC equipment enclosures, gate hasps, tool storage, and utility access points. The keyed-alike configuration is particularly useful for contractors or technicians managing multiple secured access points on a single site. The weather-resistant coating helps maintain function in harsh service conditions typical of mechanical rooms, rooftop installations, and outdoor utility enclosures.
