Wooden entrance door for commercial buildings Ellison Bronze

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 adajacent to the door. The shaft is connected in the frame header to a concealed hydraulic checking 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.
