AireMed Oxygen Tank Holder – Holds (12) E, D or M9/C Size Tanks - Heavy-Duty Oxygen Cylinder Rack for Storage and Transportation – Floor Mountable Oxygen Rack – Stylish Black Frame - 4.5" Diameter

I got these and mounted them on the hand carts (Upgraded Lifetime Home Large Foldable Push Cart Dolly | 330 lbs. Capacity Moving Platform Hand Truck | Heavy Duty Space Saving Collapsible | Swivel Push Handle Flat Bed Wagon) also from Amazon. Excellent pairing. These are well built, sturdy and are the perfect size for the carts. Now I can move 24 E tanks with very little effort.

This fit well in the trunk of my SUV and held the tanks in place easily. There is a bit of rattle between the tanks themselves at the top where they aren't encased in the frame. We solved it by putting foam pieces between the tanks so they wouldn't cling.

Product holds a dozen tanks well. Ordered two and one arrived a little bent in three of slots. Other came in fine. Glad to have gotten.

My husband has COPD. He has different sizes oxygen tanks. This fits them perfect and you don’t have to worry about them falling over.

When I arrived at my brother's place in California we had oxygen tanks for him and oxygen tanks for me all free standing in the garage. Having experienced severe earthquakes there before I was seriously frightened of all of the oxygen tanks standing on end. This product arrived quickly and allowed me to get control of the tank situation quickly. Because the height of the rack is so high, there is no way any bottle will fall over.I loved this so much that I ordered another.
