I decided to save a few dollars and buy an open package from amazon warehouse, just my luck, it was missing one of the screw covers, I went and installed it anyways. I reached out to Vevor and there was no problem in sending me a new cover. The railing is very solid and sturdy. Like others, I used tapcons (1/4\"x1.5\") instead of the supplied anchors. With the supplied anchors you would need to drill a wider and much longer hole. As it is, you could hang off it no problem. If installing in stone like my steps, you will need access to a powerful SDS hammer drill, my regular hammer drill was nowhere near strong enough and futile. My friend's SDS hammer drill made very quick work of it. Would recommend and buy again.
