This is a handy device that makes watering your lawn easier. Kinks-It attaches anywhere on your hose that’s convenient. Extend enough hose to water the area to be reached by the sprinkler. Clamp Kinks-It on the hose in-line with the side holes on device, give a slight squeeze to lock it. Set it on a hard surface like a deck, driveway or patio. With the water running simply step on this device (green pedal) as hard as necessary to shut water off. You’ll hear a clicking sound. Move sprinkler to new location, return to Kinks-It and step on yellow pedal. Device will now pop open, but remain clamped to hose. Water will again flow fully. It will not ruin your hose and will never be placed in the same area on hose twice. It’s location on hose changes with every use. To remove. Squeeze yellow pedal to top of green hinged portion and open.
