Review: Easy to install & looks nice - I have a non-standard size short flight of 3 steps to our front porch. I carefully measured and selected the "4-step" railing which fit perfectly. The installation was smooth and the railings look great. I made one small modification that made the railing much more sturdy. I had wood columns on either side of the stairs. In addition to bolting the railings to the stairs, I drilled a hole through the railing that was near the wood column, put a threaded insert into the wood column and used a 6" stainless bolt through the railing and into the column to hold the railing firmly in a third point. I don't know that it was absolutely necessary to do, but with it the railing is rock solid and held parallel to the wood column. One additional tip... I installed my railings into brick which isn't the best material. When you do that, you need to be sure that the bricks are securely cemented in and you need to watch for bricks that have holes in them and if possible keep your holes in solid portions of the bricks. In addition to the supplied masonry bolts, I used Gorilla glue in the holes and under the bracket to provide some additional holding power. This plus the bolt I described above has resulted in a perfect looking, rock solid installation.
Review: Stair railing 101 - I am not a carpenter!! So when I was told I had to have a railing I was dumbfounded on how the hell I was going to make that happen! When all else fails jump on desertcart.. As soon as it arrived I decided to jump in at get it started! The entire installation took only 20 minutes. And that’s with me doing it alone!! The instructions are easy to follow.. it comes with wood and concrete screws, and a drill bit to make installation faster! It’s a very sturdy railing. And beautiful. Definitely worth the price if you’re looking for something easy to install and looks great, definitely add attraction to my home.

### ⭐⭐⭐⭐⭐ Great Product and easy to install
*by A***C on April 20, 2019*

Great handrail. Fit our four step porch perfectly with the adjustable angle feature. InstantRail uses a workshop for autistic adults to assemble components for shipping which is so admirable. Bravo. Shipping package was very secure and arrived perfect and on time. Our guests have commented on how good the railing looks too! Glad I choose this company and product.
