Master Lock 3LHGRN Safety Padlock Laminated Steel Green

Product Description

The MASTER LOCK 3LHGRN is a green laminated steel safety padlock built for environments where locks may face physical abuse, rough handling, or harsh conditions. The lock body measures 1-9/16 inches wide and features a 9/32-inch diameter shackle with 2 inches of clearance. A 4-pin tumbler cylinder provides reliable key control, while dual ball bearing locking delivers strong resistance to prying and forced entry. This padlock is commonly installed as part of lockout/tagout procedures across industrial, commercial, and mechanical service settings. A licensed technician, maintenance professional, or safety-trained technician typically deploys this lock during energy control procedures.

The 3LHGRN is suited for lockout/tagout applications in facilities that require color-coded lock assignments. The green bumper helps identify lock ownership or department at a glance. The keyed-alike configuration allows one key to operate multiple locks of the same series, streamlining access control for technicians managing multiple energy isolation points. The laminated steel construction holds up in environments with exposure to moisture, dust, and mechanical impact, making it appropriate for use in mechanical rooms, electrical panels, valve lockout stations, and similar service locations.
