ChemShield 5407 Rectangular Leg Out Expansion Joints With Flow Liners

These rectangular expansion joints are shipped in a compressed state, in order to ensure the best possible fit between the flanges on the customer's ductwork. The belts on these joints are made from ChemShield 5407, offering exceptional protection against chemical attacks by solvents, acids, oils - as well as excellent resistance to weather, UV radiation and other outdoor environmental factors. This expansion joint also features cage nut mounting, which compensates for slight misalignment of bolt hole patterns and provides a secure and effective fit on virtually any existing ductwork flange. Additionally, ChemShield 5407 installation does not require duct disassembly, but instead is easily accomplished via slip-in between the existing duct flanges.
