For a heavier 2" OD post mounted to a vertical face, this dual-bracket facia mount adds a bottom support below the main bracket. The second contact point shortens the moment arm and splits the load, so the post carries more side force than a single-bracket mount can. It bolts to a stair stringer face, a balcony edge, or a deck rim, and it's a good fit where the rail runs a glass infill. It's 316-grade satin stainless steel for marine-grade chloride resistance outdoors and in humid air. Built to a.060" wall spec and sized for 2" OD tubing, it closes the dual-bracket facia mount line at its largest OD.
