For larger openings, an Eclipse triple track patio door is an uber-stylish and practical alternative to the bulkiness of bi-folding doors. Without having to waste valuable space on folding sashes, your panes glide neatly behind each other when opening, leaving the full space inside your room for you to enjoy.
For an unobstructed view, our slim-frame sashes come into their own. Gliding along stainless steel runners for effortless opening, our triple track design can incorporate an opening of up to six metres.

Choose from three to six sliding sashes, with the ability to open in multiple directions. You also have the option of ultra-low thresholds for improved access.
Eclipse triple track patio doors are reinforced with steel and an anti-lift system that ensures they cannot be lifted out of the frame once locked.
