CAT Winder

The Arens CAT Winder is ideally used for skylights, roof windows and top hinged windows. This allows for mounting of the CAT Winder with the eyelet pointing downwards enabling operation with the extension pole. With hot air rising towards your roof windows and skylights it is the ideal window winder to allow this hot air to escape and the room be naturally ventilated.

The CAT Winder can also be used to operate low level top-hinged windows with a handle.

For the CAT Winder to be installed on high level (out of reach) awning windows, an inverter bracket will be required so that the eyelet can be hooked into when using the extension pole to operate the window.
