Casement Window pushbar operator, designed to be mortised under the interior casement window stop. This allows the pushbar to operate the sash without removing the interior screens. A 90 degree opening for egress can be used. Pushbar awning operators are a similar design. Both are made of unlacquered polished or satin brass. Other finishes are additional. Traditional casement stays have standard winged, or new oval thumbscrew. New Contemporary style casement and awning stays now available. Designed in cooperation with Blaze Makoid Architecture to have a clean, modern look.
