Insul-Plug; 6"

SKU: 34200

6" Insul-Plug

The insul-plug blocks old, unused thimble holes in masonry chimneys. It provides a thermal break from combustibles and prevents downdrafts from entering the room.  (Note: Be sure that the hole you are trying to fill is not over 6 1/8" ID)

The insul-plug is constructed of a ceramic based fireproof insulating material. It's available in 6" and 8" diameters.

The black outside plate covers up to a 10" diameter hole.

Simply insert it in the old thimble opening and tighten the expansion screw on the face of the insul-plug. The sides expand and create a tight fit inside the thimble opening. Easy!

It can be removed by reversing the process.
