Modular cabling fixture

An apparatus for a modular cabling fixture, the apparatus comprising:

• a first structure, a second structure, and a third structure, wherein a position of the first structure, the second structure, and the third structure is based on a server rack configuration;
• a first set of members on a first end of the first structure capable of interlocking with a first set of members of the second structure, wherein at least one member from the first set of members is insertable into a first void between two members of the first set of members of the second structure;
• a second set of members on a second end of the first structure capable of interlocking with a first set of members of the third structure, wherein at least one member from the second set of members is insertable into a second void between two members of the first set of members of the third structure;
• and
• the first structure includes a first portion of a channel for routing a cable harness, wherein a position of the first portion of the channel of the first structures is based on the server rack configuration, wherein the cable harness is insertable into the first portion of the channel, wherein an upper channel of the first portion and a lower channel of the first portion are connected by a curved channel as defined by a bend radius.
