Access your tools directly from the truck side with this rail-mounted Lo-Sider truck box. The box mounts on your truck bed rails, keeping your tools easy to access and saving valuable storage space in the bed itself. These truck toolboxes are ideal for full-sized and compact pickups. Pair the Lo-Sider truck box with a Crossover, Saddle, or Gull Wing truck toolbox to maximize your truck bed storage. The durable and lightweight aluminum box is powder-coated gloss black for superior corrosion resistance and style. The stainless steel push-button locks help your tools stay secure and accessible, and a weather-resistant seal keeps moisture and dirt away from your equipment. Mounting hardware included.
