A method of installing a cable finger accessory in a cable manager includes: positioning a first semi-arcuate clamp section against a section of an extruded support member of the cable manager; positioning a second semi-arcuate clamp section, which is hingedly connected to the first semi-arcuate clamp section, against an opposite side of the section of the extruded support member such that, together, the first and second semi-arcuate generally surround the section of the extruded support member; and fastening a clamp mechanism connected to a distal end of the first semi-arcuate clamp section and adapted to secure the distal end of the first semi-arcuate clamp section against a distal end of the second semi-arcuate clamp section such that the first and second semi-arcuate clamp sections are secured against the section of the extruded support member. The cable finger extends outwardly from at least one of the first and second semi-arcuate clamp sections.
