## Description

20 Inch Black Steel Stair Step Riser, 2-Step Metal Stair Stringer, 2 Pack Steel Stair Stringer for 20" Height Deck and Outdoor Steps - desertcart.com

Review: Solid. - I got a 1-step unit and it works perfectly. BUT, you need to drill THRU the step plank and use a nut on the underside of a stove bolt or a hex head, you can NOT get a ratchet into the underside of the most rear-ward hole position. You will have exposed hex-head bolts (and a fender washer) on the top of the step. If you use a single plank you can attach from the bottom with lags and just skip the rear hole, but if you use two 6'' planks - like many normal DIY deck-builders do - you won't reach the rearward hole. You also need to supply your own 1/4'' lags to attach the step tread/plank. This is a durable and quality unit, and was exactly what I wanted, but theres only one way to attach the planks - you'll see.
Review: Sturdy and easy installation - Easy to install and sturdy. Solved my uneven last step.

## Questions & Answers

**Q: For a 7-step stair, what size bolts do I use to attach to concrete?**
A: I used 1/4 inch, but you could use 5/16. 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'.
