Andersen/EMCO Storm Door Multipoint Lock Replacements

When your Andersen or EMCO storm door lock starts showing its age, finding an exact replacement ensures your door continues to function properly and securely. MPLocks carries these specialized multipoint locks designed specifically for the 4000 series storm door line. Each lock offers the flexibility to operate as a simple single-point system using only the center deadbolt, or you can engage all three locking points—upper, lower, and center deadbolts—for maximum security when you need it.

Versatile Locking Configuration

These Andersen/EMCO multipoint locks stand out for their adaptable security options. Homeowners can choose between single-point operation for everyday convenience or engage the full three-point locking system for enhanced protection. The field-reversible handing feature adds practical value—if you accidentally order the wrong hand, simply loosen the faceplate screws and rotate the lock body to switch from left-hand to right-hand configuration or vice versa, saving time and avoiding the hassle of returns.

Precise Measurements for Storm Door Applications

Storm door hardware requires exact specifications that differ from entry door multipoint locks. These EMCO locks feature a compact 1-1/16 inch (27mm) backset designed specifically for the narrower profiles of storm door frames. The 2-1/2 inch (63mm) PZ measurement—the distance from handle center to cylinder center—is critical for proper handleset alignment. The 48-3/8 inch deadbolt spread accommodates standard storm door heights while providing secure top and bottom locking points.

Selecting the Correct Hand and Color

Determining the correct handing for your storm door lock is straightforward: stand outside facing the door, and if the hinges are on the left, you have a left-hand door. Color matching matters for storm doors since the lock mechanism is often visible through glass panels. These locks come in white and gray finishes to complement common storm door colors. While the handing can be reversed in the field, ordering the correct configuration from the start ensures faster installation.
