Amflo's No. 538HR-RET Ultra PRO enclosed air hose reel is the perfect addition to a DIY'er's home garage or a professional technician's demanding shop environment, featuring an impact resistant housing, guided automatic slow rewind system, stop anywhere auto-locking brake, 180 degree steel swivel mounting bracket, and 3' long lead-in hose. The Stop Anywhere Auto-locking Brake means no more 'listening for the click' - simply pull out hose to desired length and release, locks immediately. When done just pull the hose another 6" to unlock and rewind the hose. The high-performance 50', 1/2" nylon reinforced, premium hybrid PVC/rubber hose is flexible, non-kinking, and durable. Hose lays flat, reducing potential trip hazards, and performs great - even under severe shop conditions. Hose features 3/8-18 male NPT brass fittings, 300 PSI working pressure, ball stop, and factory installed bend restrictors that prevent the hose from weakening and breaking after repeated sharp bends. Wall or ceiling mount capability allows this unit to easily fit any workspace. Amflo is part of the Plews & Edelmann group.
