This 9 lb lock fits handles up to 5″ high and 1.25″ thick, providing robust security with a tamper-resistant design. The keyed security system includes two unique keys and does not retain a master code, offering controlled access. Choose this if you need a heavy, purpose-built lock for high-value cargo.
Limitations: Heavy weight may be less convenient for light-use applications; ensure handle dimensions match before purchase.
Weonefit Cargo Door Lock — Keyed Differently
Best for: operators needing strict access control with two unique keys per lock and no master codes. This 9 lb lock handles up to 5″ high and 1.25″ thick handles, and features a tamper-resistant, reinforced steel mechanism that secures the roll-up door handle in the locked position. The keyed-differently system reduces the risk of accidental key sharing across multiple doors.
Limitation: As with keyed-differently systems, losing keys can require locksmith support for replacement keys.

This lock emphasizes high-security stainless steel barrel components and no mounting requirements, allowing quick installation and removal. Ideal for fleets needing a balance of security and ease of use for temporary storage or occasional transport.
Limitation: The U-shaped design may not fit all door configurations; verify handle shape and dimensions before purchase.
ENFORCER 8050 Roll-Up Door Lock
Best for: those who want automatic slam locking for quick securement as doors close. The ABLOY cylinder offers increased resistance to pick attempts, while interior jaws grip carbon steel pins in the floor-mounted boot for reliable security. This option is well-suited for operators seeking a fast, consistent locking process with strong baseline protection.
Limitation: Automatic locking design may require training to ensure drivers remember to verify the lock engages on every shutdown.

Limitation: Compatibility varies by toolbox model; confirm your latch style and mounting before buying.
Buying Guide: Key Considerations For Box Truck Door Locks

- Maintenance: Consider availability of spare keys and whether the brand offers replacement cylinders or parts.
