Dura-Tech Stablehand Haynet Filler - What a fantastic idea! This StableHand is just that, it is like having another set of hands in the stable, garden or wherever you are where you need to fill a bag. Simply roll the StableHand up and place it into the opening of a hay bag, haynet or whichever bag you want to fill - the StableHand will hold the opening open for you and upright. Simply fill it up and then remove the StableHand. It is that easy!
