CR Handrail kits is a convenient, complete kit that makes railing installation better, faster, and cheaper. This improved version of outdoor baluster rail section includes both the top & bottom rails, post attachment brackets, black stainless steel screws, and square balusters with new plastic fittings to reduce water intrusion inside metal. The outdoor railing is made with zinc treated metal, allowing it to withstand more force compared to aluminum. For outdoor use whether in cold or warm, rain or shine weather, all metal parts are finished with a durable chip resistant matte black (10% gloss) powder coat finish. To comply with most local building & safety code, the baluster is less than 4" apart and design to be less than 4" above ground to make 36" height (actual product height is about 33").
