Andersen Multipoint Locks & Kits - Replacement Hardware

Andersen Multipoint Lock Mechanisms for Frenchwood and A-Series Doors

Andersen multipoint locks secure hinged patio doors at multiple points along the frame, providing significantly more protection than single-point deadbolts. MPLocks carries the complete range of Andersen lock mechanisms, including 3-point active locks for standard residential applications and 5-point active locks for Stormwatch hurricane-rated doors. These locks feature a standard 50-51mm backset and 106mm PZ (handle spacing), making them compatible with Andersen's factory handleset trim. The current stainless steel versions directly replace older gold-colored zinc dichromate models without requiring door modifications.

Matching Lock Height to Your Andersen Door Panel

Andersen multipoint locks are manufactured in specific lengths to match door panel heights, and selecting the correct size is essential for proper installation. Available configurations cover 6 foot 8 inch, 6 foot 11 inch, and 8 foot door panels, with each lock mechanism precisely engineered for its corresponding door height. The 7-digit part number stamped on your existing lock faceplate provides the most reliable identification method. All Andersen locks feature reversible handing, allowing the same mechanism to work in both right-hand and left-hand door configurations.

Active and Passive Lock Configurations

Double door installations require both active and passive lock mechanisms working together. The active lock mounts on the primary operating door and contains the handle-operated latch, deadbolt, and hooks. The passive lock secures the stationary panel with top and bottom locking bolts that engage when the active door closes. For Stormwatch door units with two operating panels, Andersen offers 5-point active locks featuring additional shootbolts at both top and bottom for enhanced wind resistance and security.

Identifying Your Andersen Multipoint Lock

Before ordering a replacement lock, locate the part number stamped into the faceplate edge of your existing mechanism. This 7-digit number beginning with "257" or "901" identifies the exact lock model, door height, and configuration. If the stamping is worn or difficult to read, measure the overall faceplate length and compare it to the specifications listed for each lock. Door panel height alone can narrow down your options, as each height uses a specific lock length designed to position the hooks and bolts correctly within the frame.
