Side Sliding Transaction Window

Our 48″W x 48″H self-closing transaction window with horizontal sliders meet all health code requirements. These self-closing units are mounted flush to the exterior wall. By simply releasing the window after serving the customer, the door panel closes automatically. With an offset in the base, and gliding on a top-hung ball bearing system, these sliders are the smoothest windows on the market. All IFSC transaction window models are glazed with 1″ insulated glass to help improve energy efficiency and help gain better control of your heating/cooling costs. IFSC-4040: Unit Size: 48″W x 48″H
