Polyurethane Duct Checker
The Duct Checker discs are manufactured from high density polyurethane giving them the toughness to clear the duct without scraping or scratching the bore walls. The discs are spaced with gaps to allow passage through tight bends. The wire rope running through the mandrel is high quality, galvanized wire.
*Safety factor is 3:1. Check the inside diameter of the ducting and contact us for sizes available.
