• a base including a plurality of walls forming an interior volume, the base including a cable attachment interface at which a cable received through the base is attached in the interior volume, the cable attachment interface comprising:
• a first mount interface, wherein a first fastener is receivable into the first mount interface and a first body opening of a first cable attachment unit;
• a positioning interface configured to receive the first cable attachment unit;
• a second mount interface, wherein a second fastener is receivable into the second mount interface and a second body opening of the first cable attachment unit;
• and
• a third mount interface, wherein a third fastener is receivable into the third mount interface and an opening at a second cable attachment unit, wherein the third mount interface is positioned adjacent to the first mount interface along a direction of extension of the cable such that the third fastener is receivable to the third mount interface and the second cable attachment unit without obstruction from the first cable attachment unit, and wherein the second cable attachment unit is arrangeable over the first cable attachment unit such that the second cable attachment unit is more distal to a base wall of the plurality of walls of the base than the first cable attachment unit to the base wall of the base.
