External Bi-folding / E4

The E4 is Centor’s premier folding door system. It has been designed for strength and is generously proportioned to meet the requirements of specifiers looking for folding solutions in medium to large residential and commercial applications. Stainless steel bearings in the pivots and carriers allow even the largest doors to be moved quietly and with fingertip ease between the open and closed positions.

Panels up to 4000mm high by 1100mm wide, and 120 kg weight can be securely installed with your choice of brass or stainless steel hardware. The brass is available as bright polished or US10B oil-rubbed bronze finish for your choice of harmonizing or contrasting appearance against the door materials. Or, for the precise, modern impact of industrial metal the brushed 316 stainless steel option is the perfect alternative. Support track and guide channels are produced in extruded aluminium. They can be supplied anodised in clear, bronze and gold or, to colour match, mill finish sections can be specially powder coated in a wide range of colours.

Stainless steel, brass and engineering plastics are used throughout to minimize the effects of corrosion and environmental discoloration. Careful material choice also means that the hardware will remain as strong as the doors it supports. And, when closed, there is nothing externally accessible that can be removed or damaged to reduce the door’s performance as a barrier. Screw fixings are concealed and hinge caps are retained by hidden fasteners. Centor’s E4 system provides the strength, tough good looks and security that you expect in a premier product.

Simple, one-handed setting of the height and a self-locking feature that ensures that once the heights are set, they stay set.
