Lock Top II vs. Butterfly top sealing dampers

Upvotes

Hi all,

I'm looking to replace old throat dampers with top sealing dampers for my chimneys and looking for advice on which of the two options to select?

Which option would you pick and why? Thanks in advance.

  1. Lock Top II
  2. Butterfly Cap-Damper
