Stackable cable hanger with latching feature

A stackable cable hanger for supporting bundles of communications cables with the center radius of the bundle spread over the opening of the cable hanger. The cable hanger includes a cable tray with an upward extending inner arm and an upward extending outer arm. A cable tray extends between the arms. An arcuate surface on the cable tray provides a gentle bend radius to any cable bundles laid on the tray. Arcuate transitions on lateral ends of the cable tray provide a curved transition between the tray and the arms. Mounting holes are on the top and bottom of the inner arm enable attachment of the hanger to a support surface and vertical stacking of multiple hangers to create multiple tiers of cable bundles. A tie down loop on the inner arm and on the outer arm enables closure of the hanger opening with a cable tie or similar closure device.
