The Iron Sleek Rink Bracket are made from high quality carbon steel and provides a strong support for rink boards, holding up to 18" of water in your ice rink. Slopes of 14 - 15 degrees can be accommodated with Iron Sleek Rink Brackets supporting the rink boards. They are easy to install, can be folded up at the end of the season and store neatly in a minimal amount of shelf space. Most importantly, they eliminate the tripping hazard around your rink!!! Keep your kids safe when running around the ice rink this winter. The days of watching your skaters, young or old, trip as they exit the rink are over!
