I figured I could drill a hole from underneath and fish the wires through this frame. I have very limited access to where I have to drill and the steel is about 3/16” thick. I tried using a 1/2” hole saw bit (the kind used for making holes in sheet metal) for rust proofing. Well , it was like cutting down a tree with a nail file. I’m going to have to devise a plan B.

Al , thanks for the info on the ability of the HF brand. I’ll pick one up tomorrow.

Which reminds me, RUSS, when you put down the ez track, did you go all the way through the frame and use a nut, or tap the frame cross tube and just bolt into the top of it?
