Poly Duct Checker
The Poly Duct Checker is designed to ensure the duct bore is clear before installing cables, utilities or facilities. These flexible mandrels are ideal for clearing debris or any partial collapse of the duct following the initial installation of the ducting.
The Series 08500 discs are manufactured from high density polyurethane giving them the toughness to clear the duct without the risk of damaging the bore walls. The discs are spaced with gaps to allow the mandrel to navigate tight bends. High quality, galvanized wire runs through the center and features dual pulling eyes for pulling from either direction.
For more information, please see the Duct Checker Mandrels Data Sheet (PDF).
