Zinc Impact Sprinkler on Fence T-Post Base with Flow Through is ideal for watering large areas. Designed to fit on the top of most metal T-posts - a sprinkler mounted on a post gives you peace of mind knowing the sprinkler will not tip over or accidently be dragged out of place. Excellent choice for multiple watering applications, including lawns, gardens, pastures, and more. The thumb screws secure the base to the post, while allowing easy removal. Impact heads have an uninterrupted water flow that are clog-resistant, even when used with dirty or reclaimed water from ponds and canals. Features a deflector shield for distance adjustment, and an anti-backsplash arm to aid in spray pattern and area coverage.
