Home IKEA HACKS Accessories Wall Décor To cover up the hideous built in AC unit in my living room wall I installed a KVARTAL panel bracket system. I mounted the KVARTAL wall hardware and single track rail above the unit. I ordered a large poster print, to be used as the “panel” with the KVARTAL top and bottom rail, and mounted it to the single track rail. Now, whenever the AC isn’t in use I can slide the poster in front of it.
