[GOTWW]

what is the main application or purpose of using inner ducts (ducts inside of ducts)? wire pulling, isolation??
thanks

yup, both. It allows pulling different cables while minimizing risk of damage to existing cables. Most commonly used for communication cabling.

1. Clifford of Vermont now has the new, plenum-rated MaxCell inner duct available
2. MaxCell provides many key advantages over traditional inner duct.
3. MaxCell can triple the capacity in a conduit. It minimizes the cost of construction of congested building cable networks and is easier to install due to fabric flexibility in difficult building cable network systems.
