Intermatic K4021C Fixed Photocontrol

The Intermatic K4021C is a 120-volt fixed-position photocontrol designed for automatic dusk-to-dawn lighting operation. It fits standard outlet boxes, post lamps, or wall packs and suits residential or light-commercial exterior circuits. The unit includes a locking nut, washer gasket, and 9-inch leads for wiring. A side-mounted 5/8-inch-18 threaded stem secures the device in place.

Check your mounting location and voltage

Verify that the supply circuit is 120 volts and that the fixture provides a standard outlet box or compatible wall pack opening. The 5/8-inch-18 threaded side mount requires a matching knockout or drilled hole with enough clearance for the locking nut. Ensure the fixed-position sensor orientation matches the desired light-sensing direction before ordering. The K4321 accessory adds a weatherproof wall plate with neoprene gasket if extra sealing is needed.

Does the K4021C photocontrol include a wall plate and gasket, or must they be purchased separately?
