Centor S4 | Corner XO-OX is specially designed to pair with two openings either side of a fixed corner window, with two screens that meet the fixed glass panels. Frameless sliding door systems and fixed lite corners are becoming increasingly popular in modern architecture given their unique ability to deliver near frameless views and let maximum natural light in. Centor’s new S4 screen variations allows elegant screening of these openings. Where previous designs would result in jambs interrupting the clean lines of frameless systems, our unique new systems are specially designed to keep wide-span openings uncluttered.
