The main feature of these brackets is the possibility to transform them into fixed brackets, by engaging the brake and as such, eliminating the offset. This not only increases the stability of the trolley, but also increases the stationary load capacity by approximately 30% with respect to the offset model.

These brackets are available in the following models:
- with top plate attachment
- with unthreaded stem attachment
- with threaded stem attachment, which allows the mobile scaffolding to be positioned horizontally, even in unlevel conditions.
