Metal-Fab Corr/Guard Aluminized Steel (AL29-4C/AZ) 4

This category focuses on 4 inch specialty gas exhaust vent components in the Metal-Fab Corr/Guard Aluminized Steel (AL29-4C/AZ) product line, organized so you can compare the details that affect fit. Metal-Fab Corr/Guard groups vent materials and wall constructions that have different applications. A material label alone does not establish that a component will fit an existing installation.

Look beyond the product name: confirm correct series, 4 inch nominal size, listed appliance application, fitting type, and mounting or termination requirements. The Metal-Fab Corr/Guard Aluminized Steel (AL29-4C/AZ) label identifies a particular product family. Nominal size alone does not establish compatibility with other brands or other venting designs.
