4. LEAF-DROPS 6 X 18 INCHES
Leaf-Drop Back-draft Dampers are used in existing furnaces and are usually installed just above the furnace take-off in the existing ductwork. They are gravity-drop and can flop down on top of the furnace opening ... or you can install horizontal stops 1 or 2 inches from the top of the existing furnace. The Leaf-drops (4) are made out of aluminum at 25 thousand's thickness (.025"). They are 6 x 18 Inches, but can be cut down to size with a pair of shears and hack-saw. You should put at least three (3) inside your existing ductwork, and again ... if you need to cut them down to size to do that, then you should do that. Back draft dampers are used when there is more than one furnace hooked up to your duct system. Each furnace should have a back draft damper with leaf-drops installed in the old, existing furnace. The Leaf-Drops are $150.00.
As you can see, we have a Back Damper for either round, rectangular openings, and leaf-drops for existing furnace retangular take-offs. Check out our other Corn Stove items listed in our Ebay Store.
