Description

What a chimney cap does

The cap helps keep rain and snow out of the flue and stove, and its screen helps keep embers in and birds and debris out. Because it twist-locks on, it comes off easily when it’s time to sweep the chimney.

What makes MightyVent different

  • All 304 stainless. Hood, collar, screen and support straps are 304 stainless, so the whole cap stands up to weather and flue gas.
  • Built-in screen. A 3.94″ tall band of sturdy stainless mesh with 0.79″ openings.
  • Twist-lock and clamp. Same 6-tooth connection as the pipe, with 1 clamp included.
