I wanted to purchase the rail kit from harman but they wanted $500.00 (OUCH) so I decided to build one my self out of kindorf (unistrutt) that I had at work (electrician) I used 1 1/2 kindorf and 3/4 kindorf for the cross rails with 3/8 hardware and 4 kindorf knees. I know its a little over kil but the material and hardware was free. I originally built one out of wood but had a hard time sliding the stove on the 2x4's So this is what I made what do you think?
