P1000 Multipoint Lock - Amesbury Truth Replacement Parts

Amesbury P1000 Multipoint Lock Gearbox Replacements

The P1000 series from Amesbury represents a reliable solution for homeowners and professionals needing to replace worn or damaged multipoint lock gearboxes. These lock bodies are engineered to fit into existing multipoint lock assemblies without requiring a complete system replacement. MPLocks carries both American cylinder and Euro cylinder versions, giving you flexibility based on your current door hardware configuration. Understanding the difference between the P1000 and P2000 series is essential before ordering, as the two lines have distinct specifications that affect compatibility with your door system.

Gearbox-Only Design for Targeted Repairs

One of the key advantages of the P1000 gearbox is its focused replacement approach. Rather than purchasing an entire multipoint lock assembly, you can swap out just the mortise lock body while keeping your existing faceplate and extensions in place. This makes the repair process more economical and less invasive. Each gearbox features a 1-inch deadbolt throw for reliable security and a 5/16-inch spindle hub that connects to standard multipoint door handles. Whether you have an active or passive door leaf, there's a corresponding P1000 gearbox to match.

Compatible with Marvin Integrity and Similar Door Systems

The P1000 series is frequently found in Marvin Integrity doors, making these gearboxes an ideal replacement option for that brand. However, the 45mm and 35mm backset options with 92mm PZ spacing are used across multiple door manufacturers. If your current lock matches these specifications, the P1000 gearbox can serve as a direct replacement regardless of the door brand. Both American and Euro cylinder configurations are available, so you can maintain compatibility with your existing cylinder hardware.

Measuring Your Backset and PZ Before Ordering

Accurate measurements are critical when selecting a P1000 gearbox. The backset is measured from the edge of the door to the center of the cylinder hole—either 35mm (1-3/8 inch) or 45mm (1-3/4 inch) for this series. The PZ measurement refers to the distance from the center of the cylinder to the center of the spindle hole, which is 92mm (3-5/8 inch) for all P1000 models. Taking a few minutes to verify these dimensions ensures your replacement gearbox will align properly with your existing door prep and handle hardware.
