Centor E2 hardware

Developed first and constantly upgraded since its inception, E2 is the perfect choice for bifold doors in private residences or light commercial applications. E2 hardware accommodates panels 3' 7" (1100mm) wide by 9' 10" (3000mm) high and 130lbs (60kg).

  • Top-hung bifold system.
  • Inward or outward opening panels.
  • Use with timber or aluminum doors.
  • Exterior or interior use. 
  • Cycle tested to the equivalent of opening and closing panels every day for 40 years.
  • Secure E2-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

Centor E2 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.

Fully adjustable

The patented Surelock 5 allows for self-locking vertical adjustment with an 5/16" (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 +/- ¼” (5mm) is possible using a Phillips-head screwdriver.

Wide Angle Technology

Our Wide Angle technology opens up 125° each side from a standard 90°, giving better views and flow to the outside patio and increased summer breezes. It is applicable to traditional even panel folding door configurations: 2L, 2R and 2L2R.

Wide Angle technology is available on our folding door hardware E2, E3, E4 and F3.

Using Centor hardware automatically grants you licence to incorporate our Wide Angle technology (*patent pending).
