FSB AFL®
Adaptively Flush-Mounted Bearing

FSB AFL®: Expanding the Range with Flush-Fitting Hardware Solutions
Two Variants. Total Freedom. Compatible with Every FSB Door Handle Design.

Minimal Form. Maximum Precision.

FSB AFL® brings a new level of refinement to the product portfolio with flush-fitting hardware solutions. The AFL rose measures just 3.5 mm in height and can be installed either flush or surface-mounted. New to the lineup: FSB AFL® lockable. Here, the locking mechanism is fully integrated into the rose itself with no separate bolt below the handle. The door locks with a simple thumb turn. A red indicator dot signals: privacy in use. Emergency access? A coin is all it takes.

FSB AFL® is a systemic solution suitable for any space, from office doors to restrooms. It pairs seamlessly with all FSB product families, is compatible with standard locks, and supports both flush and rebated door designs. The product line is based on a design concept developed by Markus Michalski, Head of Design at FSB, in collaboration with Michael Schmidt.

Made from aluminum or stainless steel—including the exceptionally sustainable Aluminum Pure finish—FSB AFL® meets all technical requirements of DIN EN 1906. The standard version is fire-rated and easy to install. Features include a high-performance spring mechanism, stainless steel substructure, and optional cover rose for doors already fitted with key roses.

Designed for Quiet Spaces with Elevated Standards

Whether in offices, hotels, clinics, or residential projects, FSB AFL® lockable delivers both discretion and visual harmony in bathrooms, meeting rooms, or patient areas. Architecture leads. The system follows.

Now Available in Two Variants

FSB AFL® is available now in both standard and lockable versions. It is compatible with all FSB lever handle models in aluminum and stainless steel.

AF-What?

In keeping with FSB tradition, AFL stands for Adaptive Flush-Fitting Bearing. It’s simple. And simply better, both technically and visually.
