4″ Wall Thimble
The wall thimble gives you a port to pass horizontally through your wall for wall exit installations. One side is flat black suitable for painting, and the other side is stainless steel. This part is made to work with traditional 2×4 or 2×6 stick framing with walls between 6″ and 11″ thick. Requires modification for exiting out the wall of structures with thinner walls like RVs.
