SKU CH-19MG-T4WM7

  • Keyed alike for simple key management

Solid Steel Padlock for Lockout and Security

The Master Lock keyed padlock is built with a steel body that resists physical attack and corrosion in industrial and outdoor settings. Keyed alike to code 3753, it lets one key open multiple locks so teams can manage access without carrying large key rings. It suits maintenance crews, facility managers and anyone needing coordinated security points.

1.5 Inch Body with Two Inch Shackle Clearance

A 1.5 inch wide steel case provides a compact footprint while the two inch shackle length clears hasps, chains and lockout devices that need extra reach. The shackle diameter fits standard lockout/tagout hardware so the lock installs directly on energy-isolation points, valve handles or gate latches without adapters. Hardened steel construction withstands cutting and prying attempts in daily use.

Keyed Alike Convenience for Multi-Lock Systems

Every lock in the set shares the same key code 3753, eliminating the need to track individual keys for each isolation point. This reduces downtime during shift changes and simplifies audits because supervisors carry one key for the whole group. The packaging delivers the locks ready to deploy in lockout/tagout programmes or general site security.
