Formed Bronze Balanced Door
Each door contains a total of six bronze panels – three on the front and three on the back – and weighs 700 pounds, making Ellison’s balanced design necessary to facilitate easy opening and closing. The construction of an Ellison balanced door is unique, in that it allows for large, heavy, and durable doors to open with ease. Traditional swing doors are attached at the frame and the door user must pull the entire weight of the door leaf. A balanced door pivots at two-thirds the width of the door, creating a balance that distributes the weight so the door is easy to open.
The inset balancing point allows for an easier opening force, even in strong winds or where significant building stack pressure exists, despite the added weight of the sturdy components.
Unlike conventional entry doors, an Ellison formed-up door features a solid sub-frame, which is made of minimum .09-inch thick material. The external door skins are spot welded at close intervals to the internal channel components, yielding an extremely durable unitized construction.
Each door is manufactured and pre-hung at Ellison before it leaves the factory, allowing any adjustments to be made so the operation of the door is honed to perfection. This process allows for easy installation and is useful for renovations, such as Blessed Sacrament Cathedral.
In addition to the superior quality and customization of an Ellison door, the company is able to provide customers the service of detailed record keeping. Every door produced is imprinted with an individual product number (similar to that of a car’s VIN number), to facilitate easy tracking and maintenance.
