Product Details

This is the largest of our popular side-mount brackets for attaching pickets and spindles to the side of a staircase. We recommend using two of these brackets per stair tread. Placement and spacing should depend on your baluster design and local building code (e.g. 4″ gap requirement). Each bracket includes a round flange with 3/8″ thread. For smaller versions, check out our P1647 bracket available in malleable iron (unfinished), stainless steel (polished or brushed satin), and brass. As noted below, this bracket is unfinished malleable iron, and should be finished using paint, lacquer, or powder-coat.

Side Bracket Dimension Details:

  • Fits 5/8″ round balusters, pickets and spindles
  • Overall width: 4-1/4″
  • Overall height: 5-3/8″
  • Overall depth: 3-5/8″
  • Wall flange base diameter: 3-3/8″ OD
  • Wall to center-point of baluster hole: 2-7/8″
  • Hole depth: 1″, no set screw

Installation Information: 

The back of the flange has a 3/8″-16 thread, and installation will depend on field conditions: if there is access to the stair tread, you can use a regular bolt, and length depends on size of stair thread. If there is no access, you can use a 3/8″ hanger bolt.

Note about Malleable Iron:

They have a slight oil film to prevent rust and corrosion. Item needs to be prepped before a finish can be applied. We suggest wiping them with a thinner or lacquer thinner, allow to dry, and then proceed with a finish. If a “natural” finish is wanted, after wiping down with lacquer thinner, apply a clear lacquer.
