Kim Hotstart Engine Block Heater - $200 (BLUE SPRINGS)

Kim Hotstart Engine Block Heater.
I bought this years ago to install on my D7 3T Dozer.
It is 240 volt 2500 watts (approximately 10 amps).
1 inch NPT inlet and outlet.
I planned to plug it in prior to my using the dozer in the winter so I didn't buy a thermostat for automatic operation.
Thermostats still available.
Ended up completing my work and selling the dozer before I installed it.
NIB just been sitting on the shelf.
Installation instructions in the box.
$200 OBO.
