HASP

Proven Locks' Door Hasp Kit collection is purpose-built for securing swing-open doors on trailers, containers, and enclosed storage — the entry point that a standard padlock leaves most vulnerable. Each hasp kit is designed to minimize the exposed hardware attackers target, pairing with Proven's puck lock system to create a closed-shackle defense where the lock body itself becomes the primary barrier. These are the right product when a basic hasp-and-padlock setup isn't enough.

Open-door trailer theft is most common at job sites and overnight stops — a crowbar under a standard hasp or a quick bolt-cutter swing can open most generic setups in seconds. Proven's hasp kits remove those attack surfaces.

• Designed for swing-open trailer and container doors
• Closed-shackle compatibility eliminates the most common bolt-cutter target
• American-made steel construction
• Pairs with Proven puck locks for a full closed-shackle security system
• Free same-day shipping
