I ripped a 2x4 and then dadoded it a half inch deep and used 1/16" aluminum plate slid that in and put a piece of 11" flex watt taped to the inside of it using the metal tape found at Lowe's.Drilled one hole on each corner and put all thread with washers and nuts through the holes to adjust the height of the heat plate.I used an in line dimmer switch to control the heat.it works great!!!
How many watts does it use?
