Recessing into a standard stud bay, this 42 in structured media enclosure hides modems routers patch panels and Av distribution gear behind a flush cover. The cold-rolled steel box measures 42.91 x 15.08 x 3.74 in overall with a 42.13 x 14.29 x 3.66 in cutout. Knockouts route power and low voltage cable cleanly, making it a tidy central hub for whole-home networking in new builds and remodels.
