I've been using these retractable air hoses a lot before I retired because there convienant, they don't take up much space & I don't have to worry about air hoses laying all over the house. I recently started using them in my shop but agravating trying to stretch them everywhere because of now using a stationary compressor.
I seen this handy device on YouTube using a 3" pvc pipe left open on both ends. I used some old rubber hoses & made a short section that would get me from my wall coupling to the bottom of the pvc. I connected one end of the RAH to this short section of rubber hose & left the other end with the female coupling hang over the top of the pvc. I have two of these made up & placed on opposite sides of my shop where I work mostly.
Stretched out about 18' on a cold day & when walked back it conveniently finds it's way back inside the pvc pipe.
