Fastway FORTRESS™ Coupler Lock
The most secure and universal trailer coupler lock available, fits virtually all 1-7/8”, 2”, and 2-5/16” tongue type trailer couplers. Made from the highest quality corrosion resistant materials, the unique design uses a hardened steel reversible “U” shaped shackle that allows the lock to fit almost any trailer coupler style, and is easily accessed from the front.
Locking and unlocking the FORTRESS is quick and easy with a front-facing key hole so there isn't anything to reach around to turn the key. The lock cylinder is smooth, making it an easy key turn. The solid engagement of the dual locking pins into both ends of the shackle provides the most security and peace of mind you can get in a coupler lock. The lock has a winged cover, protecting it from dirt, debris, rust, water, and ice.
The FORTRESS coupler lock is perfect for boats, RVs, ATV trailers, travel trailers, enclosed trailers, horse trailers, and virtually every bumper style trailer with a 1-7/8”, 2”, or 2-5/16” coupler.
