Features for cable managers and other electronic equipment structures

A cable manager and accessory system comprising:

• a backbone assembly including
• upper and lower lateral members arranged in parallel relationship, and
• a spine member interconnected between the upper and lower lateral members and oriented perpendicularly relative thereto, the spine member having an extruded construction and a generally uniform cross-sectional shape along its length;
• first and second upper support arms extending forwardly from opposite ends of the upper lateral member of the backbone assembly and in a parallel relationship with one another;
• first and second lower support arms extending forwardly from opposite ends of the lower lateral member of the backbone assembly and in a parallel relationship with one another;
• a first side wall interconnected between the first upper and lower support arms;
• a second side wall interconnected between the second upper and lower support arms;
• one or more first cable finger units that extend forwardly from the first side wall;
• and
• one or more second cable finger units that extend forwardly from the second side wall;
• wherein the one or more first cable finger units and the one or more second cable finger units are in general alignment with one another and define a cable management space therebetween, the cable management space being located in front of the spine member;
• wherein the spine member includes a pair of adjacent T-shaped ribs extending along its length, each T-shaped rib including an inward-facing ledge that extends toward the other T-shaped rib and an outward-facing ledge that extends in a direction opposite to that of the inward-facing ledge, the pair of adjacent T-shaped ribs together defining a T-slot channel therebetween;
• and
• wherein an accessory structure is secured against one or more of the T-shaped ribs of the spine member and is slidably maneuverable therealong such that a position of the accessory structure relative to the spine member is infinitely adjustable along at least a portion of the length of the spine member.
