HOPPE 16mm Roundbolt Shootbolt Bottom Gear

Replacement HOPPE 16mm Roundbolt/Shootbolt Bottom Gear for Multipoint Locks

Bottom gear assemblies form the foundation of a properly functioning multipoint lock system, securing the lower portion of your door into the frame when engaged. MPLocks carries HOPPE HLS9000-series 16mm roundbolt/shootbolt bottom gear units that combine both locking mechanisms in a single component. These parts are manufactured to HOPPE's exacting standards and are designed for seamless integration with existing HLS9000 multipoint lock assemblies. When your bottom gear fails, the entire lock system is compromised—having the correct replacement ensures your door operates as intended.

Precision Engineering for Reliable Door Security

HOPPE 16mm bottom gear components feature robust construction with spring-loaded latches and mis-handing devices that can be reversed during installation. This flexibility allows a single unit to work on both left and right-hand door configurations, reducing inventory headaches for contractors and simplifying the selection process for homeowners. The manual gear operation provides tactile feedback and dependable engagement, giving you confidence that your door is properly secured each time you lock it.

Multiple Backset Options for Accurate Replacement

These bottom gear units are available in 35mm and 45mm backset configurations to match your existing multipoint lock setup. The 16mm faceplate width is standard for HOPPE HLS9000 systems, ensuring proper alignment within the mortise pocket. Each assembly includes the shootbolt mechanism that extends into the threshold strike, providing resistance against forced entry at the bottom of the door where security is critical.

Confirming the Right Bottom Gear Measurements

Before ordering, measure your existing bottom gear's backset from the edge of the door to the center of the handle spindle hole—this will be either 35mm (approximately 1-3/8 inches) or 45mm (approximately 1-3/4 inches). Also verify the faceplate width is 16mm, as HOPPE produces both 16mm and 20mm variants. The handle height on these units is standardized at 36 inches, with the bottom roundbolt positioned at a specific distance from the handle center. Matching these specifications ensures your replacement drops in without modification.
