HOPPE 20mm manual tongue and shootbolt bottom gear assemblies provide the foundation for euro-style multipoint lock systems requiring precise handle height alignment. These 3/4-inch faceplate components feature a fixed shootbolt attachment to the gearbox, making accurate measurement from the faceplate bottom to handle center essential for proper replacement.
When a multipoint lock system relies on both tongue latches and shootbolts for security, the bottom gear assembly serves as the critical connection point between your handle operation and the lower locking mechanism. MPLocks carries HOPPE 20mm bottom gear components designed specifically for euro-style door applications where the 3/4-inch wide faceplate is standard. These assemblies integrate the shootbolt directly with the gearbox, creating a unified locking action that secures the bottom of your door into the frame when the handle is lifted.
Unlike adjustable multipoint systems, HOPPE's manual tongue and shootbolt bottom gear features a non-adjustable shootbolt connection. This fixed configuration ensures consistent engagement with your strike plate and eliminates the potential for misalignment over time. The 20mm faceplate width matches european-style door preparations, making these components ideal replacements for existing HOPPE systems or compatible euro-profile installations on residential entry doors and French doors.
HOPPE bottom gear assemblies are engineered for thousands of lock cycles without degradation in performance. The manual operation means no springs or automatic mechanisms that can wear out prematurely. Whether you're replacing a worn component in an existing system or building a complete multipoint lock assembly, these bottom gear units provide the mechanical reliability that professionals and homeowners expect from HOPPE hardware.
Because the shootbolt is permanently attached to the gearbox on these assemblies, selecting the correct handle height is non-negotiable for proper function. Always measure from the bottom edge of the 3/4-inch faceplate to the center of your existing handle spindle hole. This handle height dimension determines which bottom gear assembly will align correctly with your door's handle position. Ordering the wrong handle height means the shootbolt won't engage properly with your frame strike, compromising both security and ease of operation.
