High-Security Door Locks & Van Security Locks

Criminal-resistant. Easy-to-operate.

What makes Tufloc® high-security locks different?

Our research and development address what’s really important to customers concerned about ultra-safe and secure solutions.

Special HIGH-security Design

Tufloc’s high-security locks eliminate the weak points of the traditional padlock, the shackle and hasp.

This special design is the reason why businesses, industry, the U.S. military and government repeatedly buy Tufloc® when they want safe, reliable, cost-effective locks.

In addition to providing superb protection, the Tufloc high-security locks mount to fit inward, outward, double-swinging, sliding and roll-up doors. Tufloc high-security locks can even accommodate misaligned doors.

Our complete catalog of high-security locks includes right and left-hand orientations, as well as long wings, such as our Abloy Cylinder long wing locks, and short wings, like our Illium (Military) short wing locks, for easy mounting on a variety of doors and applications.
