Bottom-Rolling Technology Eliminates The Need For Strong Upper Beams
F3 allows for the cost-effective remodel or retrofit of any opening that previously had a sliding door. Now everyone can enjoy the benefits of folding doors, combining the pleasures of a seamless indoor/outdoor lifestyle with fingertip operation. Folding doors provide vistas, natural light, fresh air and larger living space particularly when entertaining, and unlike sliding doors, require no fixed glass panels or posts. F3 is based on simple but sophisticated technology using a range of strategically placed bearings to allow the bottom of the door to carry the weight, while remaining easy to manoeuvre.
Unlike other bottom-rolling systems, Centor controlled windows and doors glide through tracks, not rails, with movement controlled by articulated carriers, appropriately-sized wheels and side thrust bearings. With E3 new bottom-rolling technology, quality folding doors and windows are within reach of every existing building and to every door and window manufacturer. The patented system installs with simple hand and power tools and requires no structural changes to the building.
The new F3 Bottom-Rolling System for folding doors is the industry’s first comprehensive bottom-rolling hardware technology, putting folding doors and windows into any existing building space without major structural changes. Bottom-rolling systems allow the weight of the door to be transferred away from the top of the opening, eliminating the need for a strong and often restricting upper beam – freeing up more design space.
