Tri-Max® is CTS-Thompson's newest innovation in handcuffs. Tri-Max® bump and pick resistant technology will enhance officer safety during arrest and in-custody transport situations. Tri-Max® patented technology consists of a dual ratchet engaging independent retaining bars separated by a barrier called Pick-Shield-XLS®. Tri-Max® handcuffs are designed with a split-shackle construction. This increases the strength of the handcuffs by directing the gap between the dual shackles to pass through a rigid monorail retaining bar. Independently floating retaining bars on each side of the shackle are engaged by a double five-tooth pawl. Stamped from 1050 carbon steel, the parts are hardened from R885 to RC40 prior to assembly. This gives the Tri-Max exceptionally strong and allows maximum flexibility to avoid cracking under stress.

Gaining vertical and lateral strength, the internal bar also inhibits a shim from entering the nose or rear of the shackle. While popping the double lock may be possible, a pick has no straight line of sight to go through the handcuff to engage the rear retaining bars and depress them. Picks also don't stand a chance through the keyway.

Tri-Max retains three levels of integrity at:

Nose of the shackle
Rear of the shackle
Key hole

That's why it's called TRI-MAX Security! Tri-Max® was recognized as a finalist for the Law Enforcement Technology Magazine, 2020 Innovation Award.
