## Description

This vent wall thimble is a reliable ventilation accessory crafted from 1mm thick 304 stainless steel, offering exceptional durability, corrosion resistance and heat tolerance for long-term use in demanding environments. It fits standard 2.36 in. to 3.15 in. vent pipes, making it compatible with 99% of tankless water heater vent kits, direct vent wall thimbles and concentric vent systems, ensuring smooth and secure wall penetration. The adjustable telescoping design adapts to wall thicknesses from 4.72 to 9.1 in., making it suitable for both residential and commercial setups in spaces like kitchens, bathrooms and utility areas. A heat-resistant sealing gasket is included to prevent leaks, improve thermal insulation and support safe, efficient venting for gas appliances and water heaters. Precision laser welding creates a clean, professional finished look, while the included outer flange enhances the appearance of exterior walls while maintaining a tight, weather-resistant seal.
