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'. ## 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.tw/products/100181231-mtb-black-steel-stair-riser-with-1-2-3-4](https://www.desertcart.tw/products/100181231-mtb-black-steel-stair-riser-with-1-2-3-4) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-21*
