E3

E3 bifold door hardware for external applications allows for the extra weight of double-glazing in a bifold-scale opening. E3-based doors promise unprecedented insulation against noise and temperature variation when doors are closed. The ability to use sturdier door construction and materials enhances security and resistance to the elements in the most exposed of applications.

Weatherproof
Impressive water performance ratings are achievable from both outward and inward opening doors because of the way it allows door panels to close snugly against weather seals. Resistance to air infiltration up to 50 times better than a sliding door and impressive acoustic sealing quality are a resulting bonus, particularly when E3 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
Manufactured in architectural grade stainless steel, individual E3 components have undergone extensive laboratory testing including cycle testing to 50,000 operations 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
Quick-fix surface-mounted fittings allow for easy assembly and installation while still complimenting traditional joinery styling. 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 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.

Secure
No externally accessible hardware can be removed or damaged when E3-based doors are closed. Locking screw technology ensures that E3 hardware cannot be removed from the track. Centor dropbolts, door furniture and locksets complete the package.

Unobtrusive Guide Channel
Offset floor guides and floor pivots are standard allowing the floor guide channel to be concealed beneath closed doors. A range of ready-made door sills compatible with E3 simplify the installation of bifold doors in exposed applications and ensure a stylish, seamless result.
