Atrium Door Lock Replacement Parts and Compatible Hardware

Atrium doors were manufactured with European-style multipoint locking systems, primarily featuring GU Tripact and ESSVE lock mechanisms. When these original components fail or wear out, finding exact replacements can be challenging since many have been discontinued. MPLocks offers a curated selection of Atrium replacement hardware, including modern alternatives engineered to work with your existing door preparation. From complete multipoint lock assemblies to individual cylinders and strike plates, these solutions help maintain the security and functionality of Atrium entry door systems without requiring complete door replacement.

Compatible Lock Assemblies for Discontinued Atrium Systems

The multipoint locks in this collection are specifically designed to replace discontinued GU Tripact tongue version locks commonly found in Atrium doors. These replacement kits feature 3-point locking systems with two tongue latches and a deadbolt, all engaged by lifting the handle. While minor modifications may be required during installation, these assemblies use standard 45mm or 35mm backsets with 92mm PZ spacing—measurements that align with original Atrium specifications for smoother retrofitting.

Euro Profile Cylinders with Universal Compatibility

The German profile cylinders available for Atrium doors feature solid brass construction and Schlage-compatible keyways, allowing for convenient rekeying. Double keyed options provide key-operated locking from both sides, ideal for storm doors and security applications. These cylinders work across multiple European lock brands including Fuhr, Ferco, and Hoppe, making them versatile replacements when your original Atrium cylinder needs upgrading or replacement.

Understanding Atrium Lock Measurements for Proper Replacement

When selecting replacement hardware for Atrium doors, the critical measurements include backset (typically 35mm or 45mm), PZ spacing (92mm is standard for Atrium), and overall faceplate length. The PZ measurement refers to the distance from the center of the cylinder to the center of the handle spindle. Faceplate widths vary between 16mm and 20mm depending on the original lock installed. Measure your existing lock carefully before ordering, as using incorrect dimensions can prevent proper installation and door operation.
