The Capper Lift & Seal Kit is the perfect solution for creating a flush, level, and weather-tight bed rail when installing STAPLL Fender Rack Brackets with tonneau covers or bed cappers.

Whether you’re building an overland setup or upgrading your work truck, this kit helps eliminate uneven mounting surfaces while improving sealing and protection from the elements. The included rubber rolls and butyl seal rubber create a durable, weather-resistant barrier that keeps dust and moisture out, while also enhancing overall stability.
Installation is straightforward and can be completed with basic tools, making it an easy DIY upgrade. With custom-cut lengths, you can dial in the perfect fit for your specific configuration. Built to handle tough conditions and long-term use, the Capper Lift & Seal Kit makes integrating your brackets with other truck accessories simple, secure, and reliable.
