Using Arlington's single-gang adjustable floor boxes simply makes sense. It can accommodate flooring up to 2" thick, so one box can be used for many floor thicknesses. The adjustment screw is accessible at all times, so if the flooring has not been chosen yet, simply adjust the box to mount nearly flush once in place. The nickel-plated rectangular cover blends in with any decor. The two flip lids protect the receptacle when not in use.
