Review on 🔌 ARB 10900028 Threaded Socket/Surface Mount Outlet: An Ideal Electrical Solution by Douglas Holla

Threads are not visible but the ARB cooling plug screws into this socket. On my first trip, the fridge went out thinking there was no thread. But the issues are there, so I won't have this problem anymore. However, be careful not to over-tighten as the outer hole in the housing is round and will not impede the rotation of the inner connector. The inner plug is round but has two flat faces that could have been used for attachment but were not used. There is also a plastic lock nut that holds the inner plug in place and can come loose from the threads if over tightened. You'll probably want to pull it very tight, but you'll probably have to settle for that.
