RVMATE 5th Wheel Lock — Heavy Duty King Pin Lock with Anti-Theft Warning Tag

Overview

Protect your 5th wheel, king pin, and trailer from unauthorized movement with the RVMATE 5th Wheel Lock. Its sturdy build and the bright yellow warning tag create a clear signal of security, helping deter would‑be thieves whether you’re parked at the campsite, in a yard, or along a roadway.

The lock is designed for broad compatibility. It stands 83 mm tall and has an internal diameter of 74 mm, making it suitable for standard 50 mm trailer pins. This universal sizing means it can be mounted on semi-trailers, fifth wheels, trucks, boats, and many containers that use compatible pins, giving you flexibility across multiple setups.

Durability you can feel

Built from heavy‑duty steel with a welded construction, the unit is meant to endure real-world conditions. The electrostatic finish adds weather resistance and rust protection, helping the lock maintain function and appearance after exposure to sun, rain, or coastal air.

Visibility, deterrence, and ease of use

A bright yellow warning tag paired with a clearly visible lock communicates security at a glance. When it’s time to lock or unlock, the process is straightforward: engage the lock onto the king pin, then rotate the key 180 degrees to secure it. Each lock ships with its own keys for independent control.

• Solid, tamper‑resistant construction that stands up to outdoor use
• Universal fit for 50 mm king pins, broad compatibility across vehicles
• High‑visibility warning tag to signal an active lock at a glance

In everyday scenarios—long stops at industrial yards, between job sites, or while storing a trailer at a rural property—the RVMATE lock offers a practical, removable layer of protection. It’s designed to be user‑friendly without relying on power or complex setup, delivering peace of mind through a straightforward security solution.

What’s included and how it helps

Each unit operates as a self-contained security device with its own keys, enabling simple access management without shared codes. While it doesn’t promise guaranteed results, its robust materials, protective coating, and ease of use make it a practical deterrent that many trailer owners value.
