Our Innovative Concealed
Heavy Duty Door Operator System

Brookfield now manufacturers concealed heavy door closer systems for specialty installations such as the unique storefront opening shown here. The solution consists of our door operator replacing the linkage arm with a coupling connected to a special CPH upper pivot assembly that transmits torque directly to the door.  A bottom CPH pivot (not shown) is available to support the weight of the door.  Standards are available, all of which can also be customized to your specific needs.
