Stanley Security Solutions CEFBB179-54 Five Knuckle Architectural Hinge

Stanley Security Solutions CEFBB179-54 Five Knuckle Architectural Hinge is a steel, full-mortise, standard-weight hinge built for electrified door hardware, featuring a five-knuckle ball-bearing design that delivers smooth, reliable operation. It uses concealed conductor wiring with four 28 AWG conductors (four-wire) to power through-door components, such as electric locks, exit devices, or hold-open devices, while keeping the wiring hidden inside the hinge. The 4.5 in. x 4 in. footprint (model variant CEFBB179-54) is offered in Satin Chrome (US26D) and also available in other Stanley finishes, including US26 (Bright Chrome), US26D (Satin Chrome), US4 (Satin Brass), US10 (Satin Bronze), and US19 (Flat Black), as listed across Stanley catalogs and related price lists. This electrified, five-knuckle hinge is designed for secure, tamper-resistant power delivery to door hardware without exposed wiring, and it is commonly used on doors that require integrated electrical access control or monitoring hardware. Applications include doors that need power to operate electrified locks, door closers with integrated hold-open functionality, or other through-door components in security and access-control systems, making the CEFBB179-54 a precise match for through-conductor, full-mortise installations.
