The E3 delivers simple, elegant functionality for larger folding doors. Manufactured using Swiss CNC tools and precision ground bearings, the E3 accommodates door panels to 80kg and includes a range of additional features which give complete freedom in door design.

Equal sized panels
Centor's innovative hinge system provides symmetry to the door design and simplifies the door manufacturing process.

Concealed floor channel
For a more discreet appearance, offset floor guides and pivots enable the guide channel to be located under the doors and out of view, when they are in the closed position.

Simple adjustment
Easy screwdriver access and simple vertical adjustment of the patented Surelock mechanism on pivots and carriers makes the installer's job even easier. Centor's patented pivot sets uniquely provide horizontal screw adjustment of 10mm making E3 the most practical system for larger folding doors.

Tested to exceed 50,000 opening and closing actions at maximum load, without any component failure, we can confidently offer our 10-year warranty. 

Combining E3 with recommended weather-seals, door systems consistently pass a range of international weather proofing codes. Also the E3 system accommodates varying door designs so doors can be manufactured for the most severe locations.

E3 systems incorporate locking screws, secure hinges and non-removable components. Centor's dropbolts, specifically designed for use with folding doors, are substantial, robust and lockable so door systems can withstand physical attack.

Wall pivot
The floating wall pivot is used to control normal door deflection on tall doors and bowing caused by wind or climatic conditions, so maintaining a weather-proof system. It also enhances security by reducing any leverage applied to door panels and preventing their removal.
