Review on 🔌 High-Quality Tecmate OptiMATE Cable O-40: Weatherproof SAE Socket, Panel Mount for Efficient Connectivity by Pete Door

Seems perfect for what I need it for; as a bulkhead connector for a quick connection to my 4 amp charger to charge my 12 volt batteries in my cars that don't drive very often. Any charger with an SAE connector will work with it. An 11/16" (0.6875") drill bit is ideal for this. My caliper says the threads are .677" OD. Even a 3/4 inch hole will do if you don't mind it being a bit messy. The length is measured straight at 40 inches tip to tip. any quick and direct access to your 12v battery If someone wanted to steal your car with a flatbed they could use this to quickly drain the battery to disable your car alarm first. Store the port in an inconspicuous place. The fuse will be activated, so short-circuiting the battery can also cause a fire.
