Any of your readers that are about to install a railing (professional or beginner) may be interested in this product called “Spring Bolt”. I found it at Home Depot and did some research on line. This was the first railing I did in about 15 years and it turned out beautifully; better than most professional jobs I have seen recently. I must say that I was a bit hesitant at first because most of the time the “As seen on TV” and home show demos of new product do not live up to their expectations once you get them home. However that was not the case with the Spring Bolt, in fact it exceeded all of my expectations. It was extremely easy to use and much more forgiving then a rail bolt. I was able to line up the profiles exactly. One practices run on a piece of scrap and I was confident to start my railing using the Spring Bolt system. This is an amazing little product.
