Roto North America

Roto North America introduced an opening restrictor suitable for inward- and outward-opening aluminum windows. The Roto TiltFirst window handle technology prevents opened sashes from slamming shut in windy conditions. Sashes stop at a defined opening width and are locked in an end-stop position using the handle. The restrictor is controlled by the handle only. The sash is locked by moving the handle at the end stop from the 90-degree position back into the 0-degree locked position.
