The Coxreels 254 is a rubber hose stop, or hose bumper, for spring driven reels with 1/2" I.D., 3/4" O.D. hoses. Overall diameter 3-1/2". It makes an adjustable lead length for the hose and keeps the hose from retracting too far. Two screws are used to make adjustments. When installing, make sure the screws are not over-tightened so they do not damage the rubber.
