Panasonic PC-RD06C6 PC-RD06C6

The PC-RD06C6 curtain style damper measures 26.875 x 14.875 x 12 inches and weighs 34.5 lbs. Worth knowing before you get to the ceiling: at that weight it is a two-hand lift on a ladder, and most installers set it with a helper or a lift rather than trying to hold it and shoot fasteners at the same time. Check the framed opening in the wall or floor against those numbers before the damper leaves the ground.

Both. The PC-RD06C6 is a folded ceramic curtain style damper built to meet combustible and non-combustible UL assemblies, so the same part number covers a wood framed rated partition and a non-combustible one. That matters on a mixed building where you would otherwise carry two damper part numbers on the same submittal.

No wiring. It closes on a fusible link, which is a heat sensitive mechanical release, so the curtain drops under its own weight when the link separates. Nothing to power, nothing to tie to the fire alarm panel, and no actuator to commission. If your spec calls for a damper that closes on a signal from the alarm system or one that also handles smoke, this is not that device and you want a motorized or combination fire/smoke damper instead.

A curtain damper stacks its blades out of the airstream in a folded pack and drops them across the opening when the fusible link lets go. The PC-RD06C6 uses that folded ceramic curtain arrangement. A multi-blade damper instead has blades that sit in the airstream and rotate closed. Curtain types are the common choice for straightforward rated wall and floor penetrations; multi-blade types get specified where blade intrusion into the duct has to be controlled or where the damper is being driven by an actuator.
