JCJ ENTERPRISES MUD DAUBER FURNACE SCREENS
With proper use of the Mud Dauber Screen you eliminate the concern for costly repairs to the furnace as a result of fan motor loss or furnace burner blockage caused by mud daubers, wasps, mice, birds, tree frogs, spiders, etc. Install a Mud Dauber and forget these problems. This screen is sized so as not to block air flow to and from the furnace.
