Mul-T-Lock NE & NG Series

High Security Padlocks (MTL500 Key Platform)

The Mul-T-Lock NE and NG Series High Security Padlocks deliver exceptional resistance against physical attack, picking, and key duplication, making them one of the most trusted padlock solutions for commercial, industrial, and high-security environments.

Manufactured by Mul-T-Lock (ASSA ABLOY Group), the NE/NG padlock range combines hardened steel construction, boron alloy shackles, and advanced patented cylinder technology to provide a durable and highly secure locking solution for demanding applications.

When configured on the MTL™500 (MT5®) key platform, the padlocks benefit from patented key control technology designed for master key systems, key copy protection, and high-security access management.

The range includes multiple body sizes, shackle diameters, and shackle types, enabling the correct padlock to be selected for everything from gates and containers to critical infrastructure, industrial equipment, and motorcycle chains.
