Durable Carbon Steel Construction – Crafted from high-quality carbon steel and coated with a durable black powder finish, this hardware kit is designed for longevity and can support up to 300 lbs of weight, making it perfect for both home and office use. Compatibility and Easy Installation – Suitable for ladders with a thickness of 1-3/8" to 1-3/4", the sliding track has a width of 1-9/16". Ensure at least 2" of solid space on the bookcase or wall for track installation. How to Calculate Ladder Height: Please note that this product includes only the hardware and does not include the ladder. To determine the correct ladder height for your sliding system, first measure the track installation height (H) from the ground to the center of the track. Then, calculate the ladder height (L) by subtracting 2-13/16" from the track installation height (H). This ensures the ladder you purchase will fit perfectly with the track system for smooth and safe use. sliding library ladder hardware,rustic black
