This lock securely latches your coupler's handle in the closed position to prevent any unwanted decoupling.

You can also match the keys to your other Proven Locks products; simply provide your existing key code to our customer service team.

    Our stainless and aluminum versions are machined in the USA from domestic billet materials. Both options come with a durable stainless steel locking pin.
