Products / GAF Master Flow Chimney Caps (Adjustable)

Master Flow Chimney Caps (Adjustable) are GAF's adjustable-size safety caps for chimneys, held in place by an adjustable lock-jaw bracket, with a single-piece, heavy-gauge hood and epoxy powder finish. Two models, LCCA and SCCA, cover a range of round, oval and flue tile outer dimensions. GAF says they meet most fire codes and advises consulting local fire codes, and gives a 4-year limited warranty under the Master Flow Ventilation Products Limited Warranty.
