Responding to the demands of architects and homeowners wishing to push the boundaries of bifold innovation, Centor E3 is suitable for a range of residential and commercial applications. Providing complete freedom in door design, E3 accommodates panels up to 4' (1200mm) wide by 12' (3600mm) high and 250lbs (115kg), allowing for the extra weight of double-glazing.
- Top-hung bifold system.
- Inward or outward opening panels.
- Double or triple glazed.
- 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 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.
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, no mortising required.
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.
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.
Centor E3 hardware is manufactured in architectural-grade stainless steel. Carriers, guides, pivots and hinges are available in stainless steel, PVD bronze/black and PVD brass.
Bearings are custom-machined while wheels are individually precision-ground to ensure silky smooth operation.
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).
