RDP Round Base Chimney Vacuum Cap

HEAVY-DUTY CONSTRUCTION: The galvanized round base chimney vacuum cap is constructed from heavy-duty galvanized steel and is proudly manufactured in the USA | DESIGN: The unique shape of the cap increases updraft and helps prevent downdrafts caused from wind by altering the direction of the wind and creating a partial vacuum | FIT: The vacuum cap is designed to be mounted over single wall pipes and comes with a draw bolt collar to help ensure a secure fit | MULTIPLE SIZES: The vacuum cap comes in a range of sizes. We recommend ordering the same size cap as your single wall pipe.
