This Hoppe 55mm Euro profile half cylinder features a D-knob thumb turn and is designed for inactive or passive doors. The 90-degree turn mechanism provides a clear visual indicator of the lock status, allowing homeowners to easily see whether the door is locked or unlocked at a glance.

Frequently Asked Questions

What is the difference between a 90-degree and 360-degree cylinder?

A 90-degree cylinder only turns a quarter turn and provides a visual indicator of locked/unlocked status. A 360-degree cylinder can rotate continuously like a standard key cylinder.

What door thickness does this cylinder fit?

This cylinder is designed for doors that are 2-3/8 to 2-1/2 inches thick.

Can I use this cylinder on a door that requires a key from outside?

No, this is a non-keyed half cylinder intended for inactive or passive doors. For keyed entry, you would need a full Euro profile cylinder.
