I needed a larger than normal waterproof junction box for the thermal switch to control the slide heater band. Although it looks like an oversized box, it fit the bill perfectly. It looks good but won't be put to the test until next winter. The rim spacer and one side of the wires are molded in one piece, but the wire spacers on the other side are loose and easily fall out if not cared for. I sealed mine with silicone caulk.
