HOPPE 16mm Inactive Door Multipoint Lock Extensions

Understanding HOPPE 16mm Inactive Shootbolt Extensions for Double Doors

When replacing or repairing multipoint lock hardware on French doors or other double-door setups, the inactive panel requires specialized extensions that function differently from active door components. MPLocks carries HOPPE's 16mm faceplate inactive extensions, including bottom gear units with shootbolts and top extension rods. These components integrate with the HLS9000 system and feature the distinctive operation where pulling down on the serrated drive bar causes the shootbolt to retract rather than extend—a critical distinction when ordering replacement parts.

Shootbolt Function for Inactive Panel Security

Inactive door panels rely on shootbolt extensions to secure the top and bottom of the door into the frame and threshold. The bottom gear unit features a 70mm (2-3/4 inch) backset and includes the shootbolt mechanism that anchors the door when engaged. The top extension rod connects to the gear assembly, allowing the entire system to operate as a unified locking mechanism. This configuration provides the multi-point security that prevents forced entry through the stationary door panel.

Compatible with HOPPE HLS9000 Multipoint Systems

These 16mm faceplate extensions are engineered for HOPPE's HLS9000 euro-style multipoint lock platform. The 5/8-inch wide faceplate matches standard HOPPE door preparations, ensuring proper fit in existing mortise pockets. Whether you're replacing a worn extension or completing a lock assembly, these components maintain compatibility with other HLS9000 hardware including lock cases, strike plates, and handle sets.

Measuring for Inactive Door Extensions

Before ordering, measure your handle height from the bottom of the door—the bottom gear listed here is designed for a 36-inch handle height. Top extensions can be trimmed to fit, with a maximum cutoff allowance of 4-1/2 inches. Remember that inactive extensions operate opposite to active ones: on inactive panels, the shootbolt pushes out to extend and lock, while the drive bar motion retracts it. Ordering active extensions for an inactive door will result in reversed operation that won't secure properly.
