Malleable Iron side-mount bracket for attaching pickets and spindles to the side of a staircase. Bracket includes a round flange with 3/8″ threaded hole for mounting hardware (not included), and a set screw for securing the baluster (Allen key included). Available in two sizes: small (for 1/2″ round) and large (5/8″ round). In typical setups, we recommend the small when fitting three balusters and brackets per stair tread, and the large when fitting two. P1647 is also available in brass and stainless steel.
