In some instances, wasps can nest in the screw holes of the reel casing, resulting in an unsightly rust-like appearance and discharge. Hoselink's Classic Retractable Hose Reel Plugs will prevent this from happening and can be retro-fitted into any Hoselink Classic Series reel. Simply push into place in each screw hole on both sides of the hose reel unit to install. The colour matches perfectly with the hose reel casing for a discreet solution to this annoying pest problem. Ensure you order the correct pack for your hose reel size. This item is for the plastic plugs only and does not include a hose reel.
