The surface mount boxes feature a compact low profile outline. They are ideal for
retrofit situations and where internal wall access may not be obtainable. Designed for
use with HellermannTytons modular jacks and various multimedia modules, the surface
mount boxes are easy to install and can be fastened to any surface. The boxes
have knockouts on 3 sides to mate with HellermannTytons TSR single channel raceway
in 3/4 and 1-1/4 widths.
