Our "NPSR" series "Narrow Profile Supply Reels" are are "tall and narrow" and taller than most reels found elsewhere. As a result, they hold more hose than similar reels, for a given width. And their width can be adjusted for more- or less- capacity on an as- needed basis.
Our "LPSR" series "Low Profile Supply Reels" are low and wide. They are designed to be mounted on the floor or at the ceiling, in front of your vacuum reel- in line with it- not off to the side. As a result, they offer you the narrowest possible space requirement in your van or truck, so that they give you the widest floor space possible.
