Product review (5 stars): Versatile Aluminum Duct.
Are your Ducts in Good Order?  Central Services ensures your Ducts are always in order.  If you've ever seen Brazil, well you know what I mean.  This Duct was exactly what I ordered; good quality expandable aluminum duct.  I really appreciated the 5" diameter and the 8' length for my use.  I need to move/redirect some airflow to the other side of my living quarters where I'm Deployed.  I was able to form one end and duct tape (more duct stuff) to the A/C Unit, turn a short 90 deg turn and stretch the aluminum duct out the 8' over lockers and push air to the back of the conex box.  While I could have used a fan to circulate air, outlets are not readily accessible, and I really just wanted it to work when the A/C unit cycled.
