The Automatic Rotoroll Garden Hose Reel is spring-loaded powered with no tangling hose wind-up. The patented locking device guarantees safety when hose gets rewound and when in use; the locking device takes place automatically when hose is dropped accidently or can be activated by pulling quickly on the desired hose length pulled out. To unlock and rewind the hose, simply give a short tug on the hose and walk it back to the unit. The winder guide moves back and forth ensuring the hose to coil evenly and noiseless. Complete with all necessary mounting hardware, unit swivels 180-degree if wall mounted, and potentially 360-degree if floor/patio mounted. The aluminum pin is rustproof and allows easy removal of the reel in the winter time. Unit includes 66-feet 1/2-inch hose which, compared to the 5/8-inch hose, is very light but slightly reduces water flow ; the 3-layer braided hose is resistant to high water pressure handling bursting pressure of 435 PSI. Spray nozzle patterns are (clockwise) wide cone, narrow cone and straight; counter clockwise for off position. Complete with quick-click couplings for practical faucet attachment and female hose connector with water-stop feature that automatically shuts off water when hose is detached from the nozzle (to use with any other type of nozzle, male accessory adapter is needed, sold separately). Made of polypropylene and molded in glass fibre reinforced plastic that is shockproof and UV-resistant. Minimal assembly and tools required. Handles water temperature up to 104°F and outdoor temperatures up to 122°F. Unit is 100% quality controlled during manufacturing process. 2-year warranty. Made in Italy.
