HOPPE 16mm Roundbolt Top Extensions for HLS9000 Locks

HOPPE HLS9000 16mm Roundbolt Top Extensions for Multipoint Door Systems

Roundbolt top extensions form the upper portion of a complete HOPPE HLS9000 multipoint lock assembly, working in conjunction with bottom gear to deliver multi-point security along the door's height. These extensions feature the standard 16mm (5/8 inch) faceplate width common to European-style multipoint hardware, ensuring seamless integration with existing HOPPE door preparations. MPLocks carries a selection of roundbolt top extensions designed for 36-inch handle height configurations, covering door heights from approximately 72 inches to over 99 inches tall.

Precision Engineering for Reliable Roundbolt Engagement

Each HOPPE roundbolt top extension is manufactured to exacting tolerances, ensuring the roundbolt engages cleanly with corresponding strike hardware in the door frame. Unlike hook or shootbolt mechanisms, roundbolts provide smooth, quiet operation while delivering dependable holding force at the top of the door. The 16mm faceplate width is the standard dimension for HOPPE HLS9000 systems, making these extensions direct replacements for worn or damaged components without requiring door modifications.

Sized for Specific Door Height Ranges

Selecting the correct top extension depends on your total door height and handle placement. These extensions range from approximately 45 inches to nearly 62 inches in length, each calibrated for specific door height windows. The roundbolt position—measured from the handle centerline—determines where the upper locking point engages the frame, so matching the extension to your door's dimensions is critical for proper function and security.

Measuring for Replacement Roundbolt Extensions

When replacing a top extension, measure from the center of the handle cutout to the top of the door to confirm your handle height, then measure the total door height. These two measurements determine which extension length will position the roundbolt correctly within your frame's strike. If your existing extension shows a part number, that's the fastest path to finding the exact replacement—but door measurements are equally reliable when the original number isn't available.
