Long runs of 1-inch OD tubing sag without help, and this Flush Center Post supplies the middle support: the horizontal tube passes through the center of the post, steadying a long contemporary grab bar, a multi-section towel rack, or a wide-window curtain rod — no decorative ball at the joint. Offered in polished brass, 304 polished stainless, or 304 satin stainless to match modern fixtures. It is the flush counterpart to the ball-center post — the same mid-support job with a cleaner look — and pairs with the matching 340-1 flush end posts at each terminus so a full contemporary run comes from one family of parts.
