ABSTRACT:
An aerial cable spacer is provided with a cable retainer and vertically disposed strengthening tabs or ribs. The cable retainer includes a cable retaining arm. A mid portion of the cable retaining arm has a non-rectangular plus “+” shaped cross section. The plus “+” shaped cross section engages and exerts a force on the cable as the cable retaining arm bends to a closed position. The arm is flexible so as to create a resilient force in conjunction with the plus “+” shaped cross section to securely hold the cable on a cable seat of a main body portion of the aerial cable spacer. A pawl is carried on the arm at a predetermined orientation to engage a corresponding set of teeth on the spacer body for enhanced cable clamping force.
