Home / Aluminum Profiles / Door Profiles / Interior Profile / Sliding Series With Track
Interior sliding doors with unlimited linked panels, a drained embedded bottom track and an ultra-slim frame. Choose the NICE System for patented hardware details, or the Perfect System for a 5.0 mm solid-frame option.
NICE · Linked sliding door with bottom track
Perfect · Slim-frame sliding doorsMT Flying supplies aluminum sliding door profiles with a top track and a low, drained bottom track for interior doors and glass partition profiles. Panels are linked so they open together, turning a slim partition wall into a wide opening between rooms.
Both systems use the same idea — slim aluminum frames running on a top track and a low, drained bottom track, with panels linked so they open together. They differ in frame series, track options and hardware.
