Every Ellison door is 100% custom. Choices in material, finish, size, hardware, and style are only the beginning. The final design is determined by the vision of the project team and the functional needs of the project.
Ellison balanced doors made from formed stainless steel are constructed with a minimum stile width of 2-3/4” (3-1/2” preferred), a minimum top rail height of 2-3/4” (3-1/2” preferred), and a minimum rail height of 6”, though 10” is recommended to comply with 2010 ADA Standards. In most cases, the minimum face width of the frame material is 3”, and frame depth is a minimum of 5”. Glass and glass thickness may vary.
Ellison Formed Stainless Steel Balanced can be constructed to suit an architect’s design concept. The shaft containing the torsion bar closer spring can be either concealed within the formed stainless steel frame or exposed. These doors can also be equipped with Ellison PowerNow power operators.
Ellison's Revolutionary PowerNow design
An Ellison PowerNow-equipped balanced door features a low energy operator, concealed in the frame header, and an actuating arm that provides the opening force on demand. Ellison’s standard hardware provides the closing force.
When power is not needed during manual operation, Ellison PowerNow-equipped balanced doors operate the same way as standard Ellison balanced doors – the power operator is never engaged, reducing operator wear and maintaining Ellison’s signature manual ease of operation.
Any Ellison balanced door can be specified as PowerNow-equipped. Power operators are available in your choice of two leading manufacturers – Stanley and Horton.

- Life Cycle
The average lifespan of a typical high-traffic commercial entry door is about 10 years. For an Ellison custom balanced door, the expected lifespan is 80 years and counting. Many of the earliest Ellison balanced doors (from the 1930s) remain in operation to this day. This means, in time, at least seven doors would have to be manufactured to serve the duration of just one Ellison custom balanced door
Ellison custom balanced doors (excluding wood doors) are comprised almost entirely of metal and glass, two of the world's most readily recyclable and upcyclable materials. Only two very small – but critical – components are polymer-based, to ensure long term corrosion resistance. What's more, most Ellison doors are made from particularly valuable metals like bronze and stainless, which helps to ensure their eventual recycling
Ellison produces nearly the entire balanced door in-house. For example, all balanced hardware is cast in Ellison's foundry and tooled in Ellison's factory. Virtually no material is wasted, as unused material is remelted for reuse. Also, under a sustainable manufacturing program sponsored by the New York State, Ellison has implemented manufacturing systems that maximize both water and energy conservation
