ETH Energy Transfer Hinge - Command Access

Product Overview

The Energy Transfer Hinge (ETH) is the ideal way to pass low voltage power from the hinge jamb to the lockset without having any exposed wires. These hinges are commonly used with electric mortise and cylindrical locks, electric strikes (when on a pair of doors), electric exit trims, latch pullback devices, door mounted card readers and low voltage door lights. The wire chase should be drilled with a 3/8" drill bit at the point noted on the hinge template. The ETH hinge should always be positioned as one of the center hinges on the door, since the modified hinge no longer meets manufacturers load bearing specifications. A starter hole of 3/4" diameter x 1-1/2" deep is recommended for positioning the hinge wire. In fire rated conditions be sure to confirm the maximum starter hole diameter and depth with the appropriate testing agency.
