Centor E3 CLD hardware

Created to address the unique requirements of composite door manufacturers and fabricators, Centor E3 CLD brings the extraordinary potential of Centor's surface-mounted bifolding hardware to the aluminium-clad timber door market, with the design based on Centor E3 hardware.

  • Top-hung bifold system.
  • Inward or outward opening panels.
  • Use with composite doors.
  • Suitable for double or triple glazed.
  • Exterior or interior use.
  • Locking screw technology ensures Centor E3 CLD hardware cannot be removed from the track. 
  • 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

Centor E3 CLD’s innovative hinge system provides symmetry to the door design and simplifies the door manufacturing process. Modified panel gaps and frame tolerances ensure enhanced panel sealing. 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 patented Surelock 5 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.
