Even though we are in the hottest part of Summer, I know it will be Heater Time soon enough. I want to mount my Heaters, with Magnets. Will the Heater Plastic Bracket, fit in Plastic Counter Sunk Block or the Ring Magnets. The Digital Part of my Thermometers, to the outside glass. The Probes are okay, just Hanging in the Water. Also if there are other applications, post them here. Looking for the Magnet Size, Verses Mounted Item, Verses Thickness of the Glass and Acrylic.
