Buying Guide

Match baluster length to code and railing height

Measure your stair and deck rail heights and choose from available lengths (26", 29–32", 36") to meet local building codes and ensure proper spacing

Choose material for durability and maintenance

Aluminum and powder-coated steel resist rust and require less upkeep than raw iron; hollow metal spindles are lighter and easier to handle

Confirm mounting and included hardware

Select packs that include screws or compatible mounting brackets to simplify installation and avoid extra trips to the hardware store

Consider visual profile and spacing

Rectangular, square, and round profiles produce different visual effects and may affect code spacing and baluster count per run

Buy by pack size to match project scope

Choose 25–75 pack options to reduce waste and ensure consistent finish across the entire railing project
