Centor E3 hardware

Responding to the demands of architects and homeowners wishing to push the boundaries of bifold innovation, Centor E3 hardware is suitable for a range of residential and commercial applications. Providing complete freedom in door design, our E3 hardware accommodates panels up to 1200mm wide by 3600mm high and 115kg, allowing for the extra weight of double and triple glazing.

  • Top-hung bifold system.
  • Inward or outward opening panels.
  • Double or triple glazed.
  • Use with timber or aluminium doors.
  • Exterior or interior use. 
  • Cycle tested to the equivalent of opening and closing panels every day for 40 years.
  • Secure E3-based doors with Centor Dropbolts or Centor Twinpoint locks.
  • Backed by a 10-year warranty.

Dimensions are intended as a guide only. Calculated weight checks should be performed to ensure doors built to maximum height and widths do not exceed maximum weight.

Simple assembly

E3 hardware is available with straight or offset hinges. The offset hinge system allows for equal-sized panels regardless of the configuration, ensuring manufacturing is simple. Quick-fix surface-mounted fittings allow for easy assembly. 

Offset floor guides and floor pivots allow the guide channel to be concealed beneath closed doors, offering a neat appearance and preventing debris build-up in the channel. Sills are also available.

Fully adjustable

The new Surelock 5 (patent-pending) allows for self-locking vertical adjustment with an 8mm Allen key. To raise or lower the panels, simply insert the Allen key into the end of the carrier to depress the pin and wind up or down. Once adjusted, the new setting is locked into place as the Allen key is removed. 

Independent top and bottom lateral adjustment of +/-5mm is possible using a Phillips screwdriver.
