Turn the SWB14 into a flush mount enclosure! Flush mounting is ideal for hollow stud walls on 16" centers. The minimum rough opening is 14.25" wide x 14.25" high x 3.5" deep. Can be adjusted for varying wall finish thickness and this locking, removable, hinged door extends beyond the box edges approximately 5/8" which easily conceals uneven cutouts of the wallboard edges.
