Andersen Hinged Door Lock Actuator for 400 Series Frenchwood — Replacement

Overview

The Andersen Hinged Door Lock Actuator is designed to work with 400 Series Frenchwood Hinged Patio Doors, accommodating both in-swing and out-swing configurations from 1988 to the present. When you turn the deadbolt knob on the escutcheon, the actuator rotates to engage the deadbolt, helping to secure your patio door with deliberate, confident motion.

Key benefits and use cases

Replacing a worn or spinning actuator can restore smooth lock action and consistent security. This actuator is mounted under the inside escutcheon and secured with a limiting plate and two screws, making a straightforward part swap for compatible doors. It’s designed for residential use where reliable entry and exit are part of daily life.

What to know before replacing

Families and homeowners may encounter variations in international products; terms, labeling, and instructions can differ. Check compatibility with your door model and year (1988–present) to ensure a proper fit.
