Contemporary sliding glass doors save floor space while offering maximum glass area. The narrow top and bottom rails provide a modern feel and let in even more light. Andersen® Narroline® doors have a vinyl-clad wood, low-maintenance exterior, and a stainable natural pine interior; Andersen® Perma-Shield® doors are vinyl-clad wood, in and out. Additionally, the reach-out locking system provides weather tightness and enhanced security. For even more peace of mind, add an auxiliary foot-lock.
