Mid-support keeps a bold 2-inch OD contemporary handrail steady: the horizontal tube passes through the center of this post between its two end posts, with a clean flush profile and no decorative ball at the joint. The wider tube suits a stair or hallway rail long enough to need a middle post. Offered in polished brass, 304 polished stainless, or 304 satin stainless to match the rail, and paired with the matching 340-2 flush end posts at each terminus, it keeps the whole run in one family of parts.
