Coxreels EZ-SH-475 Safety Series Spring Rewind Hose Reel for air/water: 1/2" I.D., 75' 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.
