RETRUE Heavy-Duty Universal Trailer Coupler Lock — Fits 1-7/8 in, 2 in, and 2-5/16 in

Universal fit, built to endure

RETRUE's heavy-duty universal trailer coupler lock is designed to adapt across a range of couplers. With 11 locking positions, it can be adjusted to fit 1-7/8 in, 2 in, and 2-5/16 in couplers. This versatility helps you keep gear secure on the road and in storage, without the need for multiple locks.

Sturdy materials for real-world use

The lock combines an aluminum body with a high-strength A36 steel mechanism. This pairing delivers robust cut and shear resistance while remaining relatively light for handling. A wider, thicker steel U-shaped body adds to the overall rigidity, helping resist external force and tampering attempts.

Weather ready and maintenance friendly

Designed to withstand outdoor conditions, the RETRUE lock is rustproof and weatherproof. This makes it suitable for use in a variety of climates and environments, from coastal humidity to dusty rural settings. Routine care should include wiping away debris and lubricating the lock cylinder to maintain smooth operation.

Security features that matter

Upgraded lock cylinder uses a more complex mechanism and thicker keys. This design aims to provide stronger resistance to picking and forced entry while maintaining reliable performance over time. Users can expect a durable key system that supports repeated use without warping or misalignment.

Peace of mind with support you can count on

RETRUE offers a 120-day warranty and round-the-clock customer support. If anything is amiss, the team invites you to reach out via the product page question feature for assistance. The goal is to help you resolve issues quickly and courteously.
