Centor folding door hardware

Folding door hardware

From residences to restaurants and commercial projects, the ability to flexibly manage space has created overwhelming demand for Centor’s folding door and window systems. They’ve set the standard for functional, seamless transitions between spaces and changed the face of contemporary design. 

Centor invented the first bi-folding door system to meet weather-sealing standards – allowing them to be used externally for the first time without compromising interiors. Patented in 1998, all Centor bifold hardware uses this technology. Doors using the E4 system have since been certified to stringent Miami-Dade County hurricane standards, the most rigorous testing regime in the world. 

While weather-sealed bifolds create a formidable barrier against the elements, Centor’s systems can also be used internally where the ability to flexibly control space is equally important.
