The Coxreels 20214 is a rubber hose stop for spring driven reels with 1" I.D., 1-9/16" O.D. hoses. Overall diameter 5". It makes an adjustable lead length for the hose and keeps the hose from retracting too far. Two opposing screws are used to make adjustments. When installing, make sure the screws are not over-tightened so they do not damage the rubber. Note: Image is for reference, actual part may differ Ground shipping only
