The Patz hold-downs keep PatzGard in place and still allow it to expand and contract. This prevents buckling and fastener pull-out. The hold-downs also keep feed from getting under the liner. They allow the liner to be removed, if necessary. With less friction, chain wear is decreased.
Energy costs go down since it takes less power with less friction.
Noise, too, is subdued because the slick surface minimizes sticking and absorbs sound. PatzGard's slick surface in a gutter cleaner slide minimizes freeze down of flites. The liners can save gutter floor rebuilding if installed when chains are replaced. With 100 cows milking all the time, that 1.86 pound increase represents 67,890 pounds of feed intake. Now sweeping the mangers is so easy.
