Hart Cooley 5ewt B Vent Round Wall Thimble 5 Inches

Product Description

The HART COOLEY 5ewt is a round B-vent wall thimble designed to provide a safe passage for Type B gas vent pipe through interior walls. It creates the required clearance between the vent pipe and combustible wall framing, reducing fire risk during installation. This thimble is sized for 5-inch B-vent pipe and accommodates walls ranging from 4 inches to 6 inches thick. It weighs 1.83 pounds and installs as part of a complete B-vent system serving gas-fired appliances such as furnaces, boilers, and water heaters. Licensed HVAC technicians and plumbers typically handle this type of installation.

This wall thimble is suited for residential and light commercial applications where a Type B double-wall gas vent must penetrate an interior combustible wall. It is appropriate for use in new construction and retrofit projects where proper clearances must be maintained per the International Fuel Gas Code. The thimble fits walls between 4 inches and 6 inches in depth, making it compatible with standard stud-framed interior wall assemblies.
