Here is a beautiful and functional way to safely isolate a hot wood stove pipe from the surrounding ceiling/floor. It measures 16” wide and drops into a 14” hole. The center hole is 6.5” wide to accommodate 6” stove pipe. It is a two piece design. The inner piece rotates to allow hot air to rise upstairs when open. This one has been cleaned and painted. It has no chips cracks or other damage. Careful packaging
