The Centor S2 | XO configuration is a single screen that covers a sliding door opening and stops against the door handle. The second jamb is built into the far wall. XO offers insect protection, fresh air, breezes and uninterrupted views for smaller openings. Like all Centor screening systems, there are no pleats or fixed panels to interrupt the view. S2 can be paired with all new and existing doors and windows in a renovation or new build.
