Question:
Will this work on a delta gooseneck?

Expert Reply:
The Master Lock coupler lock, # 378DAT, is designed to fit a standard coupler like you would find on an A-frame trailer. It is not designed for gooseneck couplers. We do have a nice selection of gooseneck coupler locks that I have linked for you. The most popular option is Master Lock, # 2989AT. I have included a video showing how it works. It is a universal item so it should fit your gooseneck just fine.
