RETRUE Heavy Duty 4-Digit Combination Trailer Coupler Lock

Keyless Combination Security: This trailer coupler lock uses a user-set 4-digit code, providing convenient access without a physical key. The one-push mechanism makes everyday locking straightforward.

Hardened Steel Shackle: The reinforced shackle is designed to resist cutting and sawing attempts. This heavy duty trailer lock adds a physical barrier against unauthorized access to compatible trailer couplers.

1.1-Inch Maximum Span: Designed for compatible latch configurations, this combination trailer coupler lock offers a maximum locking span of 1.1 inches. Measure your coupler and verify clearance before ordering.

Outdoor-Ready Construction: Weather-resistant materials help protect the lock during regular outdoor exposure to rain, dirt, and changing conditions. The design is suitable for compatible boat, RV, utility, and cargo trailers.

Convenient Everyday Use: The keyless design and one-push locking mechanism make this trailer security lock practical for parking, storage, and travel. Always check that the lock is fully engaged before leaving your trailer unattended.

Designed for compatible trailer couplers with a maximum locking span of 1.1 inches.
