This Modular Post Saddle is the tube-cradle piece that sits at the top of a 300-series modular handrail bracket, sized for 1.5-inch OD round tube. Combine it with a short or long stem and a drilled or clean-look mounting plate to build a complete saddle post to whatever height and base you need, matching the equivalent pre-assembled 348 post. It also ships on its own as a replacement saddle for the tube-cradle piece on an existing 300 or 348 bracket at 1.5-inch OD, so a worn or damaged saddle can be swapped without redoing the whole post. Built in 316 satin stainless steel for salt air and wet exterior conditions like piers, docks, and waterfront paths.
