The 2-tab mounting kit allows you to mount a Dinosaur Electronic's UIB S or UIB S Post ignitor board in an Atwood®/Hydroflame® water heater without having to drill a hole to mount the board and risk drilling a hole in the water tank. It comes with an aluminum adapter plate (lower left), a clear small cover (lower right) to protect the UIB S or UIB S Post ignitor board (sold separately) and mounting hardware. Tough, clear, fire retardant ABS covers for universal ignitor boards. These clear covers offer protection from contamination and moisture while still allowing you to see the diagnostic LED.
