Ellison Bronze, Inc.
Overview:
In 1928, Ellison invented the balanced entrance door, and the Ellison Balanced Door continues to be the easiest-to-open of any door available. It is designed specifically to overcome the effects of heavy wind loads and stack pressure of a typical building entrance. The Ellison Balanced door requires no mechanical opener or other device for assistance. Fabricated to the highest quality and aesthetic standard, Ellison entrance doors are equipped with dependable rugged closers and checks, which are manufactured at Ellison. The Ellison Balanced entrance door is easy to open, extremely rugged and durable, saves space, permits the use of large or heavy doors, and has a headache-free checking system permitting fast maintenance. In addition, Ellison Balance entrance doors meet minimum A.D.A. specifications without the use of power door operators. Concealed overhead power operation is available if required.

Wood Entrance Doors
|
|
|
|
|
|
|
|
|
|
|
|
Ellison Balanced Wood Doors are distinctly different from conventional doors. When an Ellison Balanced Door opens, 2/3 of the door swings outward while 1/3 swings inward, thus traveling on an elliptical arc rather than the circular path required by hinged doors. This unique opening motion allows external wind loads to help, rather than hinder, the user. The Ellison Door actually pivots on two arms – located at the top and bottom of the door – which are welded to a pivoting shaft adjacent to the door. The shaft is connected in the frame header to a concealed hydraulic check-ing device, and is connected at the base to a geared floor box adjacent to the threshold. The shaft contains a torsion bar spring which provides the closing force for the door. The overhead hydraulic check and guide assembly guides the door as it opens and provides adjustable, timed closing speeds.
