Includes All Hardware, Nuts, And Bolts Needed To Install A Sliding Barn Door Video Installation Guide Included: An easy Step-By-Step video tutorial simplifies the installation process to save headaches and help provide the best experience possible. Ultra Quiet, Smooth Roll: Our premium nylon wheels have been successfully tested beyond 100,000 rolls Size Detail: - 96 Inch (8 feet) Single Piece Steel Pre-Drilled Rail: One full 96" rail is included instead of two shorter connecting rails - this is a detail critically important to your project's success. Others discretely offer two separate 4 foot rails, which is structurally less strong, more difficult to install correctly, and requires a disruptive rail connector in the center. We also pre-drill our rails every 16 inches (standard wall stud distance). - Door Width: Our hardware accommodates a wider range in door width than others. Different sized bolts for the hanger straps are included to fit door widths ranging from 1 1.25 inch to 1.75 inch. Finish Details: - Satin Black: A satin black finish is baked on through the powder coating process.
