Zero Clearance™: Striking Floor to Ceiling Beauty

Looking for a ceiling mounted sliding door?

Floor to ceiling cavity sliding doors are becoming increasingly popular in residential homes, commercial offices and retail fit-outs. They are of high quality and an effective way of creating flexible office and living spaces.

But the striking appearance achieved with ceiling mounted doors presents its own unique challenges when it comes to sliding door hardware. The modern, minimalist, clean lines demand unobtrusive hardware that is concealed out of view — this can be hard to achieve. Until now.

Triline Quality Door Systems proudly introduces TrilineZero Clearance™, built to attain clearances of 3-5mm between the track and top of the door. Aptly named, this product range is designed to achieve an architectural, clean-lined “Zero Clearance” look, creating the appearance of a modern, beautiful gliding ceiling mounted door.

Perfect for both single units and double sliding doors, the Zero Clearance™ range is available for standard and full-height sliding doors.

Apart from the minimalist hanger fittings, the Triline Zero Clearance™ range comes standard with a precision bearing bottom guide system that conceals the hardware out of the view and extends the “Zero Clearance” look to the floor.


Triline’s products have always been recognised for quality, and the Zero Clearance™ range is no exception. This ceiling-mounted sliding door system is built to last and enhanceany architectural project design. Features include:

  • For a clean-lined architectural look – track mounts flush with the ceiling
