Coxreels SH-N-350 Low Pressure Spring Rewind Hose Reel with Super Hub™: 3/8" I.D, 50' hose capacity, with hose, 300 PSI is part of our SH Series COXREELS® selection. COXREELS® SH Series “Super Hub™” spring driven hose reels, like the P Series, have a long history of dependable performance. The larger chassis and frame accommodate longer lengths and larger diameters of hose. Coxreels’ original Super Hub™ dual axle support system increases the stability during operation, reduces vibration and strengthens the structural integrity of the reel.
