Third Party Verification Claim

The fog machine and smoke pencil were used again to determine if any leaks
would be visible while the duct was under pressure. No fog was observed leaking
from any joint or seam and no leaks were detected with the smoke pencil.
The flow restrictor ring was removed and the duct pressurized again to 100Pa
and no leakage was measured. It appears that the coarse threads on the sheet
metal screws are self sealing.
In conclusion, No measured or visible leakage was observed before or after
installation of the Zip-Ez fasteners.
