Master Lock A1107KA-BLK Aluminum Safety Padlock Black

Product Description

The MASTER LOCK A1107KA-BLK is an anodized aluminum safety padlock designed for use in lockout/tagout (LOTO) programs and general access control applications. Built around a 5-pin cylinder, it ships keyed alike, meaning multiple locks in a set operate with the same key — a practical feature for facilities that need one key to control several lock points. The rectangular body measures 1.5 inches and features a 3-inch shackle height, providing clearance for most standard hasp and lockout devices. The aluminum construction keeps weight low at 0.45 pounds while resisting corrosion in typical industrial environments.

This padlock is suited for industrial maintenance, electrical panel lockouts, valve isolation, and other LOTO procedures where color-coded locks are required for personnel identification. The black anodized finish is commonly used to designate specific departments, trades, or shift assignments within a formal lockout program. Licensed electricians, maintenance technicians, and safety-compliance personnel are the primary installers and users of this lock.

Key Features

• 5-pin cylinder for improved pick resistance over standard pin configurations
• Keyed alike configuration allows one key to operate multiple locks in a set
• 3-inch shackle height provides clearance for standard lockout hasps and devices
• Anodized aluminum body resists corrosion and keeps overall weight minimal
• Black color coding supports department or trade identification in LOTO programs

Compatibility

Designed as an OEM-style replacement or direct-use safety padlock compatible with standard lockout/tagout hasps and group lockout devices used in industrial and commercial facilities.

Installation Notes

Safety padlocks used in LOTO applications must be installed in accordance with OSHA 29 CFR 1910.147 control of hazardous energy standards. Each authorized employee should apply their own lock directly to the energy-isolating device or group lockout hasp. Never share a personal LOTO lock between workers during an active lockout. Inspect the shackle and cylinder for wear or damage before each use.
