Apparatus for supporting cables

An apparatus for supporting a plurality of electrical cables passing through the apparatus from a first side of the apparatus to a second side of the apparatus, comprising:

• a first block having a bottom portion configured for attachment to a cable tray and a top interfacial surface comprising a set of guide-receiving features extending from the first side of the apparatus through to the second side of the apparatus;
• a second block comprising a bottom interfacial surface attachable to the top interfacial surface of the first block, the bottom interfacial surface of the second block comprising another set of guide-receiving features extending from the first side of the apparatus through to the second side of the apparatus, wherein the sets of guide-receiving features on the top interfacial surface of the first block and the bottom interfacial surface of the second block cooperatively form a plurality of spaced-apart passages passing through the apparatus at an interface between the first and second blocks when the first block is attached to the second block;
• and
• a plurality of guides for placement into the plurality of passages to receive the plurality of cables, wherein each guide comprises a first insert configured to engage the guide-receiving feature in the top interfacial surface of the first block and a second insert configured to engage a corresponding guide-receiving feature in the bottom interfacial surface of the second block.
