    Default Stair Railing Post in Sandstone

    I want to install a railing going up my front porch steps. What is the best way to anchor the bottom post into a sandstone stair thread?

    Using a good quality hammer drill drill the appropriate amount of holes, install lag shields and lag bolt galvanized bolts to secure the railing.

    Stainless steel bolt set into a masonry-specific epoxy.
    Sandstone is quite soft and holes in it are prone to start cracks/fissures. The epoxy is especially critical if it is a vertical hole (water trap).
    Stainless is so there's no chance ever of rust staining, or rust expansion blowing apart the stone.
    Remove not the ancient landmark, which your fathers have set.
