Learn About What’s Inside Your Door Operator

Improve Safety & Efficiency

NABCO Door Operators have different components inside that make up the retrofit kits. Each part of the retrofit kit coordinates with a part number that determines what product, configuration, and header model to use.

In addition to harness kits replacing the Opus on older NABCO door models, some retrofit kits include the Opus with purchase, replacing all mechanical components in the header. Other kits have the Opus purchased separately from the harness kit.
