Single Wall Round Ductwork
Linx spiral ductwork has mechanically-formed seam lock which prevents spiral seam slippage. Linx gasketed systems are available in round sizes up to 60″ in diameter and are an important part in a SMACNA Leakage Class 3 system.

Double Wall Round Ductwork
Linx Double Wall gasketed systems lead the industry in assembly times, leakage rates, and aesthetics. Forget about painting sealants on these joints and don’t even think about wrapping this system.

Flat Oval Ductwork
