The product was designed as a time saver to help people build stairs easily. Only having two steps for me to install made this build easier than cutting my own risers, and the risers have a nice modern look that doesn’t distract from its functionality. The steps are cut from 2”x10” treated lumber, and I used 5/16”x1” stainless steel lag bolts with marine grade washers for the underside of the steps. I would probably use 1 1/2” length in the future, but the 1” worked for this project. I would also use a 2”x12” if doing this again, but the 2”x10” board ended up working out. I pre drilled my holes on the steps and used an 11mm socket to attach the lag bolts to the underside to give a clean look. I have seen many people using various other methods, but this worked well for me. I was able to use bolts on 3 of the 4 holes on the risers to attach the steps, and that gives the steps a solid feel. To attach the stairs to the deck I used 3/8”x2 1/2” stainless steel lag bolts with marine grade washers. I had to dig out one side of the ground due to a slight grade, Overall, it took about two hours of work by myself. I would recommend using someone to help put these in place if you have more than 2 steps. This was manageable for me, but I would definitely recommend a helper to get them in place.

The hole is 3/8 , They look great I have picture of final project if you would like to see it. **Q: Could this product be used to go up 12 feet in a yard with a steep hill?** A: No. The largest unit (7 steps) rises to a height of 57 inches. You would need to check with the manufacturer regarding the possibility and advisability of using multiple units. **Q: Are ther leg brackets available? Are these designed to be joined together?** A: I don’t know if there are leg brackets. Ours are not joined together. **Q: My deck height is 10ft how long would my stringer haft to be** A: Do you want to know how many steps are needed, or the actual length of the stringer? These stringers have 7.5" height (rise), and 10" tread (run). So, a deck height of 10' (or 120") ÷ 7.5" equals 16 steps. However, if you actually meant what is the stringer length, the pythagorean theorem: a²+b²=c², where 'a' is the rise, 'b' is the run, will calculate the stringer length 'c'. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great time saver for building stairs *by S***Y on July 15, 2023* I needed some stairs for the back of our deck, and this was a great way to put some up in a short time.

Amazon got them to me faster than buying local. They were extremely easy to install and look good. And if we choose, they are very sturdy and no problem to use. ### ⭐⭐⭐⭐⭐ Worked great for what I needed it for *by S***G on May 2, 2024* Super sturdy- I just needed to add two steps onto my deck. I just laid the feet on the ground, as the steel is supportive to downward force. Not worried at all about them sinking. ## Frequently Bought Together - MTB Black Steel Stair Riser with 1/2/3/4/5/6/7 Steps - DEWALT IMPACT READY 1.5" Right Angle Attachment for Impact Driver (DWARA120) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/100181231-mtb-black-steel-stair-riser-with-1-2-3-4](https://www.desertcart.tn/products/100181231-mtb-black-steel-stair-riser-with-1-2-3-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
