Hart & Cooley® Increaser, 5-1/4 in Length, Steel, Galvanized, Domestic

The Hart & Cooley® double-wall, air-insulated B-Vent system is secured by locking joints. Properly installed, the vent won't come apart through vibration, and offers protection against vent failure or fire hazard. By using high-quality materials and skilled workmanship, our galvanized outer pipe and aluminum inner pipe provide protection against corrosion and external damage.

Hart & Cooley's simple two step engagement helps installers achieve installation quickly and easily. Simply engage pipe sections and secure by sliding the lock ring over security tabs. This unique system creates a strong connection without the use of screws.
