## Questions & Answers

**Q: What is the fully compressed length of the 8FT 4" diameter duct?**
A: 5 1/2 inches

**Q: Is this safe to vent a portable ac? ac's can get really hot.**
A: I've never owned a portable AC. If there is a 4"  circle shaped vent hole on the portable AC, it should tolerate the heat. Stationary ACs condensate water, there is no vent hole.

**Q: anyone use this for garage auto exhaust tube?**
A: I am currently using this to exhaust the air in my wood shop

**Q: Is this suitable for marine use?**
A: No paperwork came with it indicating whether it is USCG compliant (if there is such a requirement).  If you want to use it as a duct for a bilge blower, I would say go ahead and use it.  If you are concerned about fire retardancy, I suggest you contact the seller first.
