Master Lock 121T Padlock Set - Keyed Alike Steel 2-Pack

The Master Lock 121T delivers reliable security for lockers, storage units, and equipment with its hardened steel construction and weather-resistant vinyl coating. This keyed-alike set includes two padlocks that open with the same key, eliminating the need to carry multiple keys for different locks.

What Makes This Different

Unlike basic padlocks that use soft metals, the 121T features a hardened steel shackle that resists cutting and sawing attempts. The vinyl-covered body protects against corrosion while providing a secure grip during operation. The keyed-alike configuration means both padlocks in the package operate with identical keys, streamlining access control for multiple securing points.

Key Features

• Hardened steel shackle resists cutting and bolt cutter attacks
• Vinyl-covered body prevents rust and provides weather protection
• Keyed-alike system - both locks use the same key
• 5-pin cylinder provides pick resistance
• Compact design fits standard hasps and chains
• Includes two keys per lock set
• Suitable for indoor and outdoor applications

The 121T performs consistently in various environments, from gym lockers to storage facilities and equipment securing. The vinyl coating maintains grip even in wet conditions, while the precision-machined cylinder ensures smooth key operation over thousands of cycles. Security professionals often specify keyed-alike systems for facilities requiring multiple access points with simplified key management.
