Comments about Jackson Systems 8" X 8" Motorized Damper by Jackson Systems D-0808:
Replaced older models - 6 years old. New design is bulkier, thicker than older, and required cutting, enlarging the opening. Also, screw holes did not match up with earlier version. Installation took a bit longer as a result. Retroactive retrofit is always important whenever replacing and earlier model - Jackson should have considered this more when updating with a new model.
