This is our standard 1.2" Wall Eye with a 45 degree elbow on one end. This unit also has an additional 1" in length over the standard Wall Eye and can accommodate a 4 5/8" - 6 3/8" wall thickness. This is the larger elbow unit which can handle the larger cables that pass through the standard Wall Eyes including most standard 2 prong power cables. The elbow is designed to facilitate a drip loop for cables that pass through an exterior wall, and to deter entry of moisture. This unit also offers a replacement for the flush mount units and hinders the ability to see through the unit from one room to the other even on interior installation.
