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.
Centor E4 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.
Centor E4 hardware features the Surelock 2TM carrier pin locking system – adjust height with a 3/8” (9.5mm) Allen key supplied with all E4 pivot sets. Insertion of the Allen key disengages the self-locking spring latch. Once adjusted, the new setting is locked into place simply by allowing the latch to fall back into the locating slot as the key is removed.
Independent top and bottom lateral adjustment is possible using a Phillips-head screwdriver.
Centor E4 hardware is manufactured in architectural-grade stainless steel. Carriers, guides, pivots and hinges are available in stainless steel and PVD bronze finishes.
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).
