Cable Bushing for HEKA warm plates.
With these cable bushings you can drill a hole to the side or back wall of your breeder box just big enough to get the Schuko-plug of the warm plates through. After passing the plug through the hole you can simply close it by inserting (and gluing if neccessary) the cable bushing.
Just like this you can close the necessary hole and do not have to remove the power plug from the warm plates, thus keeping the terms of warranty!
