Keep your shop organized and eliminate air hose tripping hazards with this 50-foot, 1/2 in. Milton 2780-50D Steel Dual-Arm Auto-Retracting air hose reel. These reels are built to last, with all steel construction, a sturdy dual arm design, solid brass fittings, and a 3/8 in. x 50' EPDM rubber hose that is rated to 300 PSI. Great for most everyday applications. Operation: Simply pull-out hose to the desired length, listening for the clicks. Hose reel has 12 clicks per rotation to lock in place at nearly any length. To retract, simply pull a little more hose until the clicks stop, then guide the hose back into the reel as it retracts. Caution: Never let the hose whip back into the reel unguided. When hanging from a ceiling, use the adjustable ball stop so the hose is high enough that it is out of your way, yet still within reach.
