HAYRACKS Hayracks were used inside barns in England years ago, so livestock could help themselves to hay. Old hayracks became treasured antiques and came to be used outside windows as attractive planters for flowers. Unlike traditional wooden window boxes, hayracks can be used easily on walls or deck railings anywhere. Plus we now offer Expandable Hayracks that fit together to make a beautiful wall-mounted flower bed of any length. Kinsman offers a wide range of sizes - from 24" to 55" long. All are deep and generously proportioned so plants will flourish. Hand welded from study steel bars, Kinsman's Hayracks are coated in black plastic and have replaceable coco-fiber liners. They look good year-round, with changing displays of spring and summer flowers, then greens, berries and seasonal decorations during winter months.
