BulletProof Hitches Trailer Coupler Lock

 

The BulletProof Hitches Trailer Coupler Lock is designed for customers who want a durable security accessory for an unattended trailer. By locking around the trailer coupler, this product helps deter trailer theft whether the trailer is parked at home, at a jobsite, at a storage lot, or on the road.

This product family is available in Medium Duty and Extreme Duty configurations. Both versions use a hardened solid steel lock bar, a pick-resistant locking mechanism, a weather-resistant rubber cap, and a universal design compatible with most common trailer coupler sizes.

The Medium Duty Coupler Lock is the cost-effective option. It features a 1/2" hardened solid steel bar and is a strong choice for customers who want reliable coupler protection without stepping up to the larger Extreme Duty lock bar.

The Extreme Duty Coupler Lock is the heavier-duty option. It features a 1" hardened solid steel bar and a cut-resistant design, making it the better choice for customers who want the most robust coupler lock configuration in this product family.

Both versions come with two matching keys and are treated with an aircraft-grade lubricant for lock longevity. BulletProof also notes that these locks can be purchased keyed alike to other BulletProof locking products when ordered in matching bundle configurations.

Whether customers are upgrading for trailer security, jobsite storage, camper protection, equipment trailer security, utility trailer theft deterrence, or peace of mind while parked, the BulletProof Hitches Trailer Coupler Lock delivers a durable coupler-locking solution in Medium Duty and Extreme Duty configurations.
