View full detailsInactive euro cylinders serve a critical function in multipoint lock setups, particularly on double doors where one leaf remains stationary most of the time. These HOPPE cylinders integrate seamlessly with HLS9000 hardware, providing reliable deadbolt control from the inside without requiring keyed access from either side. MPLocks carries a range of configurations to match different door thicknesses and handleset styles, from crescent knob designs to D-knob thumb turns that pair specifically with Dallas trim.
Many of these inactive cylinders feature a 90-degree rotation mechanism that gives you immediate visual confirmation of your lock status. When the thumb turn sits horizontal, the door is unlocked; when vertical, it's secured. This simple design element eliminates guesswork, especially useful on passive doors that don't see daily traffic. The clear positioning helps homeowners quickly verify security before leaving or retiring for the night.
Choosing the right cylinder means matching both measurements and aesthetics. Crescent knobs, H-knobs, and D-knobs each correspond to specific HOPPE handleset lines. D-knob cylinders, for example, are purpose-built for the Dallas handleset trim and provide a cohesive look when paired correctly. Available finishes including satin nickel, polished brass, oil rubbed brass, and dark bronze metallic allow you to coordinate with your existing door hardware.
Euro profile cylinders are measured from the center screw hole to each end. For inactive cylinders, the inside measurement (where the thumb turn sits) is the critical dimension, while the exterior portion remains minimal since it doesn't extend through the door. Common configurations include 31.5/10mm for standard 1-3/4 inch doors and 45.5/10mm for thicker 2-3/4 inch doors. Always verify your door thickness before ordering to ensure the cylinder sits flush and operates smoothly.
