A flat brass cap rail needs a clean way to sit on top of its pickets, and that's exactly the job this connector does. It links the cap rail to each vertical picket or baluster so the top rail runs straight and secure — along a staircase, around a balcony, or across a porch. You'll use one at every picket, so it's the part you reach for most when building out a cap rail run, whether that's a short flight or a wraparound porch. It's made of hand-polished solid brass, with a finish that stays consistent across the whole brass cap rail family. That uniformity matters when a rail has dozens of connectors in view — they all read the same. Pair it with the solid brass cap rail extrusion, corner bends for direction changes, and scroll or square end pieces to finish a rail out from one matching line of parts.
