About this item

  • The Perfect Fit for 21.3" Decks: Specifically engineered for a standard 21.3 inch rise, this 3-step stringer simplifies DIY installation. Whether you're connecting a sloped yard, upgrading a porch, or adding a platform transition, it provides a seamless, professional-grade connection. Ideal for both new builds and replacing rotted wooden steps.
  • Sturdy & Durable Metal Step Stringer: Crafted from heavy-duty 4.5mm thick steel with solid welds and a rust-resistant powder coating, this staircase stringer is built to endure harsh weather conditions and stand the test of time outdoors. Supporting up to 500 lbs, it provides a strong, safe, and clean-looking solution for adding functional steps to your ladders or outdoor stairs.
  • Everything You Need Included: Say goodbye to multiple trips to the hardware store. Our pre-drilled stringers feature extra bolt holes for maximum stability. We provide the full kit: tapping screws, a specialized drill bit, and a wrench. Whether you're a pro or a first-timer, you can achieve a secure, wobble-free installation in a fraction of the time.
  • Versatile Compatibility & Modern Design: Upgrade any space—from contemporary backyard decks and patios to garages, basements, and job sites. This universal stair riser is compatible with wood treads, and securely mounts to concrete, brick, or wooden foundations. Simply add your preferred tread material to build custom stairs or step ladders quickly, combining a clean modern look with reliable structural strength.
  • Fit for 2–5 Steps: Available in 2, 3, 4, and 5-step options for different deck heights, these pre-cut stair stringers install quickly with no complicated measuring or cutting. For the best fit, ensure your deck height is slightly higher than the stringer rise. Recommended for use with wood treads (not included) at least 1” (2.5 cm) thick and 10–12”(25–30 cm) wide. One stringer supports tread lengths up to 24” (60 cm) , while two stringers are recommended for wider steps over 24” for enhanced stability and safety.
