Security Door Controls PTH-4Q 4-Wire Power Transfer Hinge

Carry four conductors across a door's hinge side while maintaining a hinge-based wiring path for an electrified opening. Security Door Controls PTH-4Q combines a 4-wire power transfer arrangement with a 4.5 x 4.5 inch hinge footprint. It is specified in finish code 626, allowing the finish requirement to be matched alongside wiring and hinge-size requirements. In an access-control door assembly, the hinge transfer bridges the moving junction between frame-side wiring and equipment installed on the door. The four available wires can be allocated by the door-system design, subject to the electrical requirements of the connected equipment. Select the hinge footprint against the door and frame preparation before installation; the listed size is 4.5 x 4.5 inches. This configuration fits openings that call for four wires rather than a higher conductor count, with the stated 4.5 x 4.5 inch size and 626 finish. Wire count, hinge dimensions, and finish code are the key attributes for matching the transfer hinge to a prepared opening. Match electrical load requirements, door handing, preparation details, and connected locking or monitoring hardware within the overall door-system design.
