Centor Architectural Window & Door Hardware System
 Even a casual glance at the E3 system gives a strong impression of Centor’s commitment to quality, but it’s only upon closer inspection that the attention to detail really becomes apparent. Stacked with standard features and with an abundance of options to choose from, Centor E3 looks even better up close!
Materials and Finishes
E3 carriers, guides, pivots and hinges are available in brushed stainless steel for a modern industrial look, Oil Rubbed Bronze powdercoat or a PVD brass finish over stainless steel should a more traditional finish be required. Head tracks, sills and floor guide channels are produced in extruded aluminum with the option of bronze and satin anodized. Both sills and channels have black polypropylene liner.
Panel Size and Materials
Centor’s innovative hinge system enables all door panels to be made the same size regardless of the door configuration (eg 3L2R or 1L4R). The easily installed hardware can be teamed with ordinary ‘book end’ door panels in wood, aluminum, PVC or fiberglass.
Concealed Floor Guide Channel
Floor guides and floor pivots have been offset so that the floor guide channel is located directly under the doors when they are in the closed position. Beneficial from an aesthetic perspective this design feature also reduces opportunity for dust and debris to enter the channel.

Aluminum door system specifications may vary from the above. Consult
your aluminum door supplier for details. Minimum panel thickness of
35mm (1 3/8”) allows for weather seal seating on panels correctly. Panels which exceed 2 ¼” (57mm) in thickness or which are below 24” (600mm) in width require special consideration in construction.
Materials such as soft timbers may not be suited to production of large, weighty doors. Materials should be of sufficient strength that screws cannot pull out. Concerns about material choice should be referred to a joiner
experienced with Centor’s bifold systems.
Wall Pivot
A floating wall pivot is used to control door stile deflection and bowing on tall doors caused by wind loads or climatic conditions. When using tall doors (over 7’4” high), use of four rather than three hinges at each junction is recommended.
Dropbolts
Easily installed with a dedicated router bit available from Centor, DF and DO dropbolts are available in a range of lengths and finishes to suit every E3 application. Available keyed and non-keyed, the clean-lined DF and DO dropbolts anchor doors firmly in the closed position and, together with the weather seals, eliminate rattling in strong winds.
Screening
E3 is fully compatible with the ES3 insect door screen, Centor’s superbly effective, world-first integrated screening solution for bifold scale openings.
