For a long wall-mounted run of 1.5-inch OD tubing, a common handrail diameter, this Flush Center Post adds mid-support with a minimalist look. The horizontal tube passes through the center of the post, holding the run steady between its two end posts, with a clean flush profile and no decorative ball at the joint. Use it along a hallway, corridor, or contemporary stair where a long modern handrail needs backing in the middle. Offered in polished brass, 304 polished stainless, or 304 satin stainless to match the rail. It pairs with the matching 340-1H flush end posts at each terminus so the whole run goes together from one family of parts.
