ABSTRACT:
A modularized electric box system provides a minimum of modular elements, typically two or three from which a basic anchor box may be formed with protruding members for support by a building body, and from which gangable extensions thereto may be fashioned. The modules may constitute a basic open front electrical box frame having at least one open side with interlocking structure for receiving and supporting either a sidewall panel or a gangable U-shaped extension box module. An anchoring box may be formed with anchoring structure integrally protruding from end panels thereof adapted for attachment to a building body. Thus minimally a basic U-shaped box frame module without sidewalls interlockable with a similar module and a removable sidewall module interlockable upon a U-shaped box frame at the open sidewalls will form a gangable box system. Interlocking channelwork permits unimpeded insertion and removal of modules by sliding movement perpendicular to the open box fronts. Thus, low cost retrofit installations may be made from a minimal inventory of parts to add one or more expansion boxes for creating a ganged system with little damage to the original wall site.
