At the Core: The FSB Adapter Technology

The proprietary adapter solution replaces numerous custom variants and reduces complexity. Instead of countless individual models, a single modular component accommodates a wide range of door and window types—functionally refined, easy to install, and built to last.

Benefits at a Glance:

  • One Adapter for Virtually All Applications

  • Quick to install, easy to retrofit

  • Significantly reduced storage requirements

  • Compatible with all door and window systems

  • Highly compatible with existing components

Installation Advantages

  • The adapter rose is pre-installed on the door or window without the door handle or cover rose.

  • No need to screw past the handle neck which saves time during installation

  • Separate female handle and adapter results in simpler installation and less risk of damage, as they can be mounted at the end of the construction phase

  • Even force distribution protects lock and hardware—for maximum durability

The result: Less effort, lower costs, and a smart system that’s quick and reliable to deploy.
