Master Lock Co 3T Laminated Padlock 1.5 in Keyed Alike 2 Pack

Product Description

The MASTER LOCK CO 3T is a laminated steel padlock sold in a two-pack with keyed-alike cylinders, meaning both locks operate with the same key. Each lock body measures 1.5 inches and is built from laminated layers bonded together for added resistance to cutting and impact. The shackle extends 0.75 inches with a diameter of 0.28125 inches (9/32 inches). This padlock is suited for securing gates, tool storage, lockers, and service vehicles on job sites. It is commonly specified by contractors, facility maintenance crews, and service technicians who need multiple locks on a single key for streamlined access control.

The 3T padlock is appropriate for light-to-medium-duty applications in residential, commercial, and industrial settings. Its keyed-alike configuration makes it practical for job-site lockout staging, equipment yard gates, and utility enclosures where one technician or crew needs to operate several locks without carrying multiple keys. The carded retail packaging also makes this two-pack easy to inventory and reorder for supply stocking purposes.

Installation Notes

Installation requires no tools beyond threading the shackle through a hasp, latch, or chain link. Verify shackle clearance matches the hasp opening before installation. For lockout/tagout (LOTO) applications, follow OSHA 29 CFR 1910.147 procedures and confirm the padlock meets your facility's LOTO program requirements before use. Do not force a closed shackle — inspect the cylinder and shackle for damage before each use in safety-critical applications.
