This component fits into the sill and allows the door frame or sidelight to be installed directly on top. No need to end mill the bottom of the frame to match the sill profile. This makes installation faster, cleaner, and far more efficient, especially for on-site applications.

By supporting the frame along the sill edge, the black rubber infill block helps maintain a tight, weather-resistant seal while streamlining the setup of composite, timber, or aluminium door systems.

It’s a reliable and time-saving solution for any installation using the Proline AM5Ex threshold system, whether in residential or commercial builds.
