Measuring 4.5 inches x 4.5 inches, this hinge integrates concealed wiring into the hinge barrel, allowing low-voltage control signals or power to pass through the door without exposed cables or power transfer loops. The satin stainless steel finish provides corrosion resistance suited to commercial door frames and high-traffic openings. It is installed by licensed electricians or access control technicians as part of a complete electrified door hardware system.\u003c\/p\u003e\n\u003cp\u003eThis electric hinge is used in commercial and institutional door assemblies where power or signal transfer to electrified locksets, electric strikes, or door hardware is required. It is a direct mortise hinge replacement that eliminates the need for separate power transfer devices at the door frame. Typical installations include office entry doors, corridor doors, and secure room access points where concealed wiring is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-wire configuration supports low-voltage control signal or power transfer through the hinge barrel\u003c\/li\u003e\n  \u003cli\u003e4.5 inches x 4.5 inches hinge leaf size fits standard commercial door preparations\u003c\/li\u003e\n  \u003cli\u003eSatin stainless steel finish for durability and corrosion resistance in high-use environments\u003c\/li\u003e\n  \u003cli\u003eConcealed wiring eliminates exposed cables or external power transfer devices at the door edge\u003c\/li\u003e\n  \u003cli\u003eCompatible with BB1191-style hinge base for simplified retrofit into existing door prep\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement electric hinge for commercial door assemblies requiring a 4.5 inches x 4.5 inches 4-wire electrified hinge with a BB1191 hinge base configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or certified access control technician.
