This is enough to make rods and brackets for 2 windows:
-metal conduit pipe (come in 10’ pipes, I used 3/4”)
-3” corner braces
-2 pkgs EMT conduit brackets to match the pipe size you choose (officially called one-hole straps, 4 in each pkg)
-1 pkg of 1/2” machine screws and nuts
-You will also need screws and anchors to attach your rod brackets to the wall (not pictured)
I already had the thin white rods (1/2”) pictured at the top, and wanted to reuse them as the inside rod, so I bought a set of 3/4” straps and a set of 1/2” straps.
