Created for grand scale commercial and residential applications, the E4 hardware system has substantially increased height, width and overall measurement specifications. Double glazed panels of previously unimaginable size, framed with the sturdiest materials move aside effortlessly with E4.

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

Concealed floor guide
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 10 mm making E4 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 E4 with recommended weather-seals, door systems consistently pass a range of international weather proofing codes. Also the E4 system accommodates various door designs so doors can be manufactured for the most severe locations.

E4 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.
