Steel Duct Checker
The Steel Duct Checker is designed to ensure the duct bore is clear before installing cables, utilities or facilities. After the initial installation of the ducting, it is often a requirement that certain sized mandrels be pulled through the ducting to ensure that there has been no collapse or obstruction in the duct.
The Series 08400 mandrels feature steel discs that are tumbled to ensure no burrs, minimizing the risk of damaging the ducting, while the spacers allow for easy bending around corners. The wire rope running through the mandrel is high quality galvanized wire with dual pulling eyes allowing the user to pull from either direction.
For more information, please see the Duct Checker Data Sheet (PDF).
