Room Treatment Progress / 4330_left_trap_installed The left side trap fits much better. Why not full height? Well, I had 6 feet worth of Auralex foam and the wood that made the frame came in 6 foot lengths. Saved time, and it creates a nice plant shelf. The panel that will go next to the trap will need to be custom cut to leave room for the AC outlet. The duplex gang box is already sitting there with some cryo Hubbels waiting to go in there.
