Arens Midi & Mini Operators with Chainheads

The Arens Mini and Midi Operators are light duty remote window winder that are capable of opening single sashes.  They are ideal for operating windows in domestic settings as they are unobtrusive and easy to install.

In a domestic setting, the Midi and Mini can provide an alternative to the MDCR when looking for a remote window winder for a high level window. Once installed they allow the occupant to open and close the window as they desire, providing natural ventilation for the room without the need for electricity.

Mechanically, they both perform the same function, but the elongated cover on the Midi hides the run off tube that comes from the bottom of the Mini operator.
