FLOOR: Our barn door running tracks are specially designed to keep the bottom bracket flat on the floor, preventing scratches from screws, bolts, or nuts, providing greater stability and a clean appearance. No grooves or holes are required in the floor, making it ideal for carpets or tiles. Easy and Quick Installation and Adjustment: Two sliding door tracks with two screws and eight mounting options allow for flexible installation. Detailed instructions and tools are included for easy setup. Adjust and tighten the screws at the bottom to properly position and secure the three wheels. Sturdy and Dependable: The high-strength solid steel base with a black powder-coated finish complements various decor styles and ensures long-lasting visual appeal. High-precision POM rollers operate smoothly, leave no marks, and enable quiet, wobble-free door movement. General Safety Instructions: The sliding door tracks are rust-resistant and durable, suitable for various interior and exterior applications. Designed for single or double barn doors, they can be used in bedrooms, closets, bathrooms, living rooms, kitchens, pantries, dining rooms, and garages.
