The Forney high performance, serve service expansion joint is designed to take the most extreme movements without inducing unneeded loads into the adjacent duct.
Forney designs round or rectangle expansion joints that are built to the customer’s dimensions.
When selecting an expansion joint it is important to understand stress induced loads passing from one flange to the other thru the expansion joint. Compression, expansion and lateral movement are critical in a long lasting, low maintenance duct system. Forney takes all these factors into consideration when designing our expansion joints.
