This is the most basic of tube rails we can make. Is what makes this one special is our use of square tube, instead of round; and the over-sized anchor plates at the base. The square tube allows people who are unstable to grip better. And the anchor plates were designed for two reasons: to locate new positions for the anchors because the previous two rails had cracked the concrete around the corner; and to allow for extra anchors on the side of the concrete adding a bunch of lateral strength to a straight rail. Bottom line, this rail is way stronger than this nice couple will ever need and won’t need to be replaced again.
