Mountain Laurel Railing comes in easy to install sections. These sections are all custom built to match what you’re looking for in your deck railing design. As you can see in the video above, the typical section is built with two boards of red cedar 2×4 at the top and bottom. The branches from the mountain laurel tree are then artistically fastened to the boards to create interesting patterns and shapes. No two sections are the same since the branches really give this railing system its unique character.
