DCD Steel Duct Checker, 4″ Duct
The Steel Duct Checker™ is designed to ensure the duct bore is clear before installing the cable or other utility. Following 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 08400 Duct Checker discs are tumbled to ensure no burrs and the spacers ensure easy bending around corners. The wire rope running through the mandrel is high quality, galvanized wire. Safety factor is 3:1.
