Stackable universal pitch cable trough system

A universal panel for receiving cabling components is disclosed. The panel includes a plurality of panel segments that are interconnected to form panel modules. The panel modules are interconnected to provide a panel of any desired length, extending from the floor to the ceiling if desired. A panel segment includes a first alignment feature and a second alignment feature. The first and second alignment features are disposed to engage a second alignment feature and a first alignment feature, respectively, on a second panel segment to form a panel module. Each panel module includes a coupler and a receiver. The coupler of one panel segment is disposed to engage the receiver of the other panel segment. Each of the panel segments further includes a first alignment feature and a second alignment feature. The first alignment feature of one panel segment is disposed to engage the second alignment feature of the other panel segment. According to one aspect of the invention, the plurality of interconnected panel segments are identical.
