Master Lock MLS7KA-P305 Laminated Steel Padlock

Product Description

The MASTER LOCK MLS7KA-P305 is a laminated steel padlock designed for medium-security applications in commercial, industrial, and trade environments. The body measures 1.125 inches wide and features a hardened steel shackle with a 3/16-inch diameter and a shackle height of 9/16 inches. The shackle width is 1/2 inch. Keyed alike to key number P350, this padlock is well-suited for operations that require multiple locks opened by a single key, reducing the number of keys a technician or facilities worker must carry. Licensed tradespeople, facility managers, and service contractors are the typical end users.

This padlock fits general-purpose lockout and access-control needs across HVAC, electrical, plumbing, and facilities maintenance. The keyed-alike configuration makes it practical for gang lockouts on equipment panels, gate hasps, or storage enclosures where a single keying system improves workflow efficiency. Its compact body width of 1.125 inches fits standard hasps and lockout devices commonly used in trade service environments.

Key Features

• Laminated steel body construction for durability and weather resistance
• 1.125-inch body width fits standard trade hasps and lockout devices
• Hardened steel shackle with 3/16-inch diameter resists cutting
• Keyed alike to P350 — multiple locks operate with one key
• Dual bumper design helps protect the shackle and body from impact

Compatibility

Keyed alike to Master Lock key number P350. Designed as an OEM-style replacement or addition to existing P350-keyed padlock sets for use with standard trade lockout hasps and security hardware.

Installation Notes

Installation requires no tools beyond proper hasp or locking hardware. Always verify the hasp or staple diameter is compatible with the 3/16-inch shackle before installation. When used in LOTO (lockout/tagout) applications, follow OSHA 29 CFR 1910.147 procedures and ensure the lock is assigned to a single authorized employee per control of hazardous energy requirements. Inspect the shackle and body periodically for corrosion or wear in outdoor or high-moisture environments.
