FAQs About Heavy-Duty Trailer Coupler Lock - Fits 2" & 2-5/16" Couplers

Please measure the ​​inside diameter​​ of the coupler's latch mechanism (the hole where the hitch ball goes). If it measures approximately 2 inches or 2-5/16 inches, this lock will fit.

The ​​tough powder-coated finish​​ is specifically designed to defend against rust, corrosion, and harsh weather, making it ideal for long-term outdoor storage. The included ​​orange dust caps​​ also protect the internal lock mechanism from moisture and dirt.

​​Four keys​​ are included with each lock. This makes it easy to share access with family members, keep a spare in your truck, or have backups in case one is lost. Since each lock has a ​​unique key code​​, you cannot get a generic replacement. We recommend storing one key in a very safe, memorable place. If the key is indeed lost, please contact our customer service team to get a solution.
