Special handles

This is a well-known type of fittings, which combines the function of handles with safety devices and / or other mechanisms. For example, a door handle with an additional padding that protects the lock from being knocked out or drilled out comes in handy. And in the bathroom or toilet, the handle can have a signaling cover (free-occupied). Typical special-purpose handles for interior doors serve as stationary and lever handles at the same time - they are used as handles in headsets. A similar device is known for fire doors.

There are also variants for doors made of different materials, either solid or profiled.
