Raising the rail is what the taller stem is for: this pre-assembled post cradles a 2-inch OD rail in a saddle at the top of a long stem fastened to its base plate, holding the rail higher off the mounting surface than the low version. That suits an elevated bar rail, a footrail, or a raised cap rail at the larger tube size. Built in 316 satin stainless steel for salt air and constant moisture, it serves exposed outdoor rails — an elevated cap rail on a pier, a raised 2-inch bar or counter rail on a waterfront patio, or a raised platform edge along the water.
