The Sterling Aluminum Railing Kit provides a crisp, clean look, pairing a breadloaf top rail (1.645 in. x 1.720 in.) and a square bottom rail (1.250 in. x 1.375 in.) with 0.60 in. square pickets. The Sterling combines the weatherability, strength and low maintenance of aluminum while meeting nationwide IRC building codes. Available in textured black or textured white color options. The textured finishes add distinction and complement your deck or porch.
