INSTALLING SQUARE AND RECTANGULAR DAMPERS -
EzySlide™ TYPE “S”
The EzySlide “S” damper is designed to be inserted in an existing or new rectangular duct from the
bottom, top, or side of the duct. Cut a slot 5 inches wide by any required length. The slot should be cut
to 3/4-inch from each duct corner (Fig 14a). This will avoid the need to cut into the “Pittsburgh Lock” in
the duct and leave sheet metal for the mounting plate screws. Slide the damper into the duct at an
angle to avoid cutting the gasket (Fig. 14b). Position the flat side of the blade to face airflow (not the
side with the connecting rods). Fasten with sheet-metal screws (Fig. 14c).
