Static Pressure Probe Plugs (Bag of 100)
The Minneapolis Blower Doors DG08-PLG-BAG is a bag of 100 red static pressure probe plugs. The plugs are an easy way to fill drillholes left in duct work after Digital TrueFlow and static pressure testing. They allow for easy removal for future testing and feature a tapered design to plug holes between 0.25 through 0.3 inches in diameter.
