Trimax Puck Lock

High‑security, hidden‑shackle lock for trailers, gates, trucks, and storage units.

The Trimax Puck Lock is engineered for maximum theft resistance using a solid, hardened steel or aluminum body and a fully concealed internal shackle. Its “hockey puck” design eliminates exposed shackle points—making it extremely difficult for thieves to cut, pry, or drill. Ideal for securing trailer door hasps, cargo doors, gates, and commercial equipment.
