E2 is a bi-fold door hardware system for door panels up to a maximum of 60 kilograms. Available in an extensive range of finishes, E2 is the smart choice for matching hardware to a range of residential and light commercial applications which do not require the extra panel weight capacity of E3 bi-fold doors or the substantial heavy door capacity of the E4 bi-fold system. E2 offers all the space-creating benefits of the larger systems in a refined yet economical package.

Impressive water performance ratings are achievable from both outward and inward opening doors with the system achieving its superior rain and wind resistance in part from the way it allows door panels to close snugly against rubber weather seals. Resistance to air infiltration up to 50 times better than a sliding door and impressive acoustic sealing qualities are a resulting bonus, particularly when E2 is used indoors. A floating wall pivot is used to control door stile deflection and bowing on tall doors caused by wind loads or climatic conditions.

Proven Performance
Produced in the highest grade stainless steel, solid brass, aluminium and engineering grade plastics, individual E2 components have undergone extensive laboratory testing including cyclic testing to 50,000 cycles as well as corrosion testing, structural testing and finite element analysis. Stainless steel bearings are custom machined to fine tolerances and machined wheels are individually precision ground to an ultra-fine hone. Unparalleled performance is the result from this top-hung design, with smoothness of function that has to be felt to be believed.

Assembly, Installation and Adjustment
With a choice of quick-fix surface-mounted fittings or mortice hinged components for more traditional joinery styles, assembly and installation couldn't be easier. Centor's innovative hinge system allows for equal-sized door panels regardless of the configuration. Comprehensive instructions are included and drill jigs are available to ensure precise placement of fittings. The patented Surelock carrier pin locking system ensures that once heights are set they stay set. Vertical and lateral adjustments can be made by the end-user, simply using a screwdriver.
