The BulletProof Extreme Duty Coupler Lock protects against trailer theft. With a 1" hardened solid steel bar, pick-resistant lock and cut resistant design this coupler lock is the ultimate in trailer protection. This lock can also be purchased keyed alike to other BulletProof Locking Products.

Our universal design is compatible with most 1-7/8", 2", and 2-5/16" couplers.

All BulletProof locks are treated with an aircraft-grade lubricant for longevity. The locking mechanism is protected by a heavy-duty rubber cap and comes with 2 keys.
