The SeQual Eclipse Wheelchair Pack attaches to any push handled wheelchair, using adjustable buckle-style clips. This harness easily attaches to the back handles of the wheelchair for transport without any added hassle.  Although designed and sized specifically for the Eclipse 5 Portable Oxygen Concentrator, the Eclipse Wheelchair Pack is compatible with all Eclipse Systems. The Eclipse fits into the main compartment either with or without the Eclipse Profile Cart (#7092) attached. The Velcro flap allows easy access to the battery.
