Belknap Hill Trading Post Backyard Ice Rink Kit with 20-foot X 40-foot Liner Play ice hockey, broomball and figure skate in your backyard with this kit; pre-built corners take the prep work out of installing the ice rink. Corners are rounded on the inside for non-stop ice hockey. Great way to keep active and have fun in freezing weather. Durable, unfinished wood components and a heavy-duty, weather-resistant plastic liner will let you enjoy the rink for winters to come. Unfinished wood corners are pre-assembled for faster and easier installation - simply slide perimeter boards into slots, join boards with stakes and add liner. Reusable plastic liner designed to fit a 17-1/2-foot x 37-1/2-foot rink. Each wood corner section measures 9.25 inches (H) x 20.5 inches (D) x 20.5 inches (W). Designed for 2-inch (D) x 10-inch (W) x 10-foot (L) perimeter boards, but other sizes can be used. (Larger rink can be made using your own liner and additional lumber.) Kit includes 4 corners, liner, 28 joiner stakes and detailed instructions. Perimeter boards not included. Freight shipment. Carrier will contact you to arrange delivery.
