Description
The BT8L Auto Gooseneck trailer coupler lock is a” high security” lock designed to fit the POP-UP brand auto latch coupler. The housing is made of ¼” P&O steel, providing durability and strength, and is tamper-proof from hammering, prying, sawing, and resistant to grinding. The Locking pin is constructed from ¾” steel and is completely contained in the housing with no access to tampering. All components are interlocked, eliminating loose parts that require assembly each time you install or remove the lock from the coupler. This feature makes installing and removing the lock quick and easy, requiring only one hand in as little as 10 seconds. This is the only “high security “ lock that is accessible vehicle-friendly.
Bolt Lock with Storage Bracket, sold separately, provides a secure place to hold your lock when it is not connected to the trailer coupler.

I spent all summer looking for a gooseneck hitch lock for my trailer. I bought and returned maybe five before giving up entirely. Then, a friend was unlocking hers and I saw her BTSS lock and gawked! It looked like what I needed so I asked if I could try it on my trailer. It fit well enough so I went straight to the website to order. Upon arriving at the website, I saw my exact hitch. My gooseneck has a lever and none of the other sellers could accommodate that style. I received it very fast (I’m local so that helps) and it fit like a glove! I’m so happy that I can travel with confidence now. Thank you BTSS for a high quality lock and great service!!
