    • The ‘S’ Type Ductwork Stiffener is fitted to the outside of ductwork between the cross joints to strengthen and stiffen the ductwork whilst also reducing vibration.  Unlike rolled steel angle, the stiffener provides a simple and economical method of stiffening ductwork, without the need for secondary protection.
    • Pre-drilled pilot holes ensure an easier and quicker fitting time by drilling stiffener and ductwork for fasteners in a single operation. Our ‘S’ Type Ductwork Stiffening is also more convenient as it can be fitted after the ductwork jointing system has been fitted.
