Frequently Asked Questions
What is an electrified hinge?
An electrified hinge is a special hinge with concealed wires that transfer power and signals between the door and frame. At National Lock Supply, we stock UL-rated electrified hinges designed for maglocks, electrified locks, and exit devices requiring discreet power transfer.
How do they compare to power transfer devices?
Both serve to route wiring through a door, but electrified hinges are concealed and integrated into the hinge itself, while power transfer devices are surface-mounted to the frame and visible.
Where are electrified hinges used?
They are installed on doors with electrified locks, card reader-controlled entry points, strikes, and panic exit devices, ensuring seamless wiring without exposed cables.
How many wires are available?
Electrified hinges are offered in 2-wire, 4-wire, 8-wire, and up to 12-wire configurations, depending on whether the door hardware requires simple power only or additional monitoring and communication signals.
Are electrified hinges UL certified?
Yes. Many models are UL-listed for fire-rated doors, ensuring safe operation under life safety requirements.
What finishes are available?
Finishes include Satin Chrome, Polished Brass, and Dark Bronze, designed to match commercial door hardware.
Do they require special prep?
Yes. Both the door and frame must be drilled to route wiring through concealed pathways, making professional installation recommended.
Can they handle heavy doors?
Yes. Heavy-duty Grade 1 electrified hinges are engineered for high-cycle commercial doors, including steel and security doors.
Are they ADA compliant?
Yes, when paired with electrified locks, levers, or operators that meet ADA standards.
