The 50 mm main blade incorporates a 400 by 600 mm rectangular vision panel made with two tempered panes, while the narrower companion blade remains opaque. Manual swing operation serves routine entry and occasional wider passage. A compatible metal frame surrounds the pair, with a lever lockset providing conventional operation at the principal leaf.
