Master Lock 7 Keyed Padlock Dual Bumper Medium Security

Product Description

The MASTER LOCK 7 is a keyed padlock designed for medium-security applications in trade and light industrial environments. The steel body measures 1.125 inches wide and features a dual bumper design that protects the lock body and surrounding surfaces from impact and wear. The hardened steel shackle is 3/16 inches in diameter, 9/16 inches tall, and 1/2 inch wide, providing a solid barrier against cutting and prying. Each lock ships keyed different, meaning no two locks in a purchase share the same key. At 0.23 pounds, it is compact and easy to deploy across multiple points of control.

This padlock is suited for residential and light commercial use cases including securing tool storage, equipment enclosures, gates, lockers, and utility panels. Electricians, HVAC techs, and plumbers commonly use padlocks of this type to comply with lockout/tagout (LOTO) procedures during equipment service. The dual bumper construction makes it a practical choice for outdoor or shop environments where the lock body may contact metal surfaces or be exposed to rough handling.

Installation Notes

Installation requires no tools beyond ensuring the hasp or locking staple is rated for the shackle diameter and load requirements of the application. Always de-energize or shut down equipment before applying lockout hardware in LOTO scenarios, following OSHA 29 CFR 1910.147 procedures. Inspect the shackle and body for wear or corrosion before each use in outdoor or high-humidity environments.
