No mounting holes show on this post body: the hardware sits concealed beneath the base, so the low saddle post stays clean-faced where exposed fasteners would spoil the look, at the larger 2-inch tube size. Otherwise it mounts a rail the same way as the drilled version, cradling the round tube in a saddle on top. Built in the same 316 satin stainless marine grade for salt air and moisture, it is the clean-look choice for a waterfront rail — an outdoor 2-inch bar rail on a patio or terrace, a gallery or museum courtyard edge, or a curated public path along the water.
