Cable trough for managing fiber-optic cables

A method of sizing a cable management trough member, comprising:

• cutting a trough member to a first length along a first plane, the trough member defining a base including a planar top surface extending along a longitudinal axis between a first end and a second end, a first sidewall, a second sidewall, and an intermediary divider positioned between the first sidewall and the second sidewall extending upwardly away from the planar top surface, wherein a base of the intermediary divider coupling the intermediary divider to the planar top surface defines a materially weakened area;
• cutting the intermediary divider to a second length along a second plane parallel to the first plane, wherein the second length is shorter than the first length;
• and
• bending the intermediary divider relative to the base to cause the materially weakened area to break, thereby enabling separation of a portion of the intermediary divider from the base.

A cable management system comprising:

• a trough member including:
• a base defining a length extending between a first end and a second end along a longitudinal axis, a width extending between a first side and a second side along a lateral axis, and a thickness extending between a planar top surface and an opposed facing bottom surface along a vertical axis;
• a first sidewall coupled to the first side of the base and a second sidewall coupled to the second side of the base, the first sidewall and the second sidewall extending upwardly a first distance above the planar top surface of the base;
• an intermediary divider positioned between the first sidewall and the second sidewall, the intermediary divider extending upwardly a second distance above the planar top surface of the base between a base portion and a top edge portion, wherein the intermediary divider defines a materially weakened area in proximity to the base portion to aid in separation of a portion of the intermediary divider from the base.
