InfratechDual Duplex Stack Switch, Surface Mount Control W/Weatherproof Cover, 14-4325

I'm using this to control 2 Infratech heaters, each with 2 heating elements. Following the simple wiring diagram, my electrician easily connected the 4 switches to these 2 heaters - with each switch controlling a single heating element. A great way to manage the amount of heat for each of the heaters by turning on one or both elements, short of using one of Infratech's slightly more expensive rotary regulators (15 amps max, and I'm not sure if they can control each heating element in an Infratech dual element heater).However, the exterior / outdoor outlet box wasn't the same with the 2 that I purchased (a couple of months apart). The first came with 3/4 inch threaded 'holes' for connectors (just what the electrician needed), while the second instead came with 1/2 inch 'holes' (not what the electrician needed). Both purchased from the same seller, so baffled why they were different. And the electrician had to find another box with the needed 3/4 inch 'holes'. I was tempted to reduce the rating by one star for this discrepancy, but am overall very happy with this product.

The box itself is good, but I bought a double switch that would control 2 heaters and so it has 4 switches total, which is supposed to be one for each bar. But it only works for 2 bars. Hope that helps

trust Infratech the products are great
