Insertion Mounting
Cut a 4” slotted opening in one side of the duct and slide the damper in. Secure the damper to the duct with the supplied
sheet metal screws. Larger sizes may require additional support by securing the back of the damper as well. If using duct
board, additional support can be obtained by using Model DBA Duct Board Adaptors.
