HOPPE 16mm Four Roller Bottom Gear for Euro Locks

HOPPE HLS9000 Four Roller Bottom Gear for Euro Multipoint Locks

The four roller configuration represents one of the most secure options in the HOPPE HLS9000 multipoint lock lineup. These bottom gear assemblies form the foundation of your locking system, housing the main lock case along with two of the four total rollers. When paired with the appropriate two-roller top extension, you achieve balanced four-point engagement along your door frame. MPLocks stocks these components in common backset sizes to help you restore full functionality to your European-style multipoint door hardware.

Manual Locking Operation and Secure Engagement

These four roller bottom gear units feature manual locking operation, meaning the handle must be lifted to engage the rollers into their strike positions. Once lifted, turning the thumbturn or key locks the rollers in place for secure multi-point contact with the frame. This design provides reliable security while giving you tactile confirmation that all locking points are properly engaged. The 16mm (5/8 inch) faceplate width is standard for HOPPE HLS9000 systems, ensuring compatibility with existing door preparations.

Available Backset Sizes for Proper Fit

Choosing the correct backset is essential for proper lock function. These bottom gear assemblies are available in both 35mm (1-3/8 inch) and 45mm (1-3/4 inch) backset configurations. The backset measurement is taken from the edge of the door to the center of the handle spindle hole. Measuring your existing hardware before ordering ensures you receive a component that drops into your current door preparation without modification.

Handle Height and Roller Positioning

These bottom gear units feature a 36-inch (914mm) handle height, with rollers positioned at specific intervals below the handle for optimal frame engagement. The first bottom roller typically sits around 15.75 inches (400mm) from the handle, with the second roller near 29.5 inches below. Confirming these measurements against your door and existing strike plate locations helps ensure the replacement gear aligns properly with your frame hardware for smooth operation.
