Master Lock 140TRI Solid Brass Padlock with Key, 3 Pack – Corrosion-Resistant & Secure

Overview

The Master Lock 140TRI Solid Brass Padlock with Key arrives as a practical 3-pack designed for everyday security across bags, cases, and lockers. The lock body is a solid brass block measuring 1-9/16 in. (40 mm) wide, built to hold up against corrosion in varied environments. The shackle is a 1/4 in. (6 mm) hardened steel diameter, 7/8 in. (22 mm) long, offering added resistance to cutting and wear.

Security design is more than strength—it’s a thoughtful arrangement for real-life use. A 4-pin cylinder paired with dual locking levers helps deter common attempts at tampering, while the compact form makes it easy to carry and access when you’re on the go.

Durability and design

From the moment you handle the padlock, you’ll notice a sturdy, reliable feel. The brass body resists corrosion in damp environments, and the hardened steel shackle stands up to routine wear. The internal mechanism combines a 4-pin cylinder with dual locking levers to discourage picking and prying.
