Constructed from stainless steel with a sleek black finish, this cap emphasizes durability and weather resistance.

The Round Base Chimney Vacuum Cap by RDP focuses on heavy-duty construction and wind-driven performance. Made in the USA from galvanized steel, the cap is designed to increase updraft and reduce downdrafts caused by wind, thanks to its distinctive shape. A draw bolt collar helps secure a tight fit over single-wall pipes, ensuring a reliable connection that resists displacement in gusty conditions. The design also aims to improve overall flow, which can contribute to better drafting and reduced backdrafts. This option is a robust choice for homeowners who want a durable, wind-optimized solution that’s compatible with common single-wall piping.

The product emphasizes a secure fit with a draw bolt collar for single-wall installations, ensuring a stable and durable cap in varied weather. While sharing core features with the other RDP option, this listing underscores compatibility with standard 6″–8″ flue configurations via its mounting method and galvanized build for long-term resilience.
