AWNING TYPE WINDOWS
(hinged from the top)

WIRE ROPE

These windows were made by KM. The design is easily recognisable as it has a wire rope winder, a pair of torsion springs, and no hinges.

When these winders break they cannot be repaired or serviced. We provide a conversion which uses an Australian-made chain winder (either locking or non-locking).

ROTO

These awning windows used an arm-winder with a short extended flexible extension riveted to the end of a standard arm. The winder is generally mounted to one side of the centre of the window.

When an old arm-winder is broken we replace it with a new arm-winder. Unfortunately the new type restricts the opening to about 800mm and is not available with a lock.

OPTION:

A better alternative is our full conversion which is more secure, more durable and provides a larger opening of about 1200mm. This option is available with or without a built-in lock.
