First, Size Matters, for the 3 steps that needing a railing I purchased the 47-inch railing. In my application I installed the railing to the landing/platform (see picture). This made it EXTREEMELY BENIFICAIL when exiting the home, you do not have to bend down to grab onto the railing when exiting.
If you have 3 steps purchase the shorter railing and install it on the 1st step down from the top(as I seen in most other 3 step applications in reviews about this product) the railing would be to short at the bottom if it is installed on the landing platform OR you would have to bend down to reach the railing if installed on first step. Look at picture and think about how you enter and exit your home. I fell this 47 inch railing work best for this 3 step application.
Product is made in China. When installed it is a Sturdy railing! It is Aluminum will not rust when salt is applied to the steps in winter it may eventually get pitted and weaken after years when the Chinese machine coating wears off.
The cheap Chinese lag bolts/anchors that come in the box should be tossed in garbage as soon as open the box they are complete junk. Since, this is a "security railing” you do not want this thing to come loose when a 250lb person lose their footing/falls/leans on this railing hard. I purchased 3 3/4" long 3/8-inch diameter Wedge Bolts (studies state to be one of strongest in concrete) at Home Depot. Need 8 of them at ~$2.50 each. If you are installing into concrete, you will need 3/8" concrete bit at least 5" long and a hammer drill (Home Depot, Lowes rent or maybe your neighbor has one).
When installing put the railing completely together first (you can see EXACTLY how it will look when installed and that it is installed straight). There is a metal cap that covers the concrete bolt heads that I put a piece of tape to hold up on railing while drilling the anchors.
Drilling concrete Anchors: I drilled the concrete holes with the railing in place. I drilled the concrete holes for the anchors right through the metal railing mounting holes. If you mark the holes and with the railing in place and then move it to drill the holes, If you are off (drill moves when drilling) you will NOT be able to get concrete anchors in the holes. Obviously, if you try to redrill the holes will be larger and anchors will not hold. Again, I found easy to drill with the railing in place. No surprises when installing and is in exact place and it straight.
Hope this helps someone since there are absolutely no instructions include in the box. Probably a good thing, since we all seen translated Chinese instructions before.
