4″ Wall Thimble
The wall thimble gives you a port to pass horizontally through your wall for wall exit installations. This part is made to work with traditional 2×4 or 2×6 stick framing. Would not be suitable as is for exiting out the wall of structures with thinner walls like RV's. *Parts ship free to lower 48 US states.
