Aluminum Stair Balusters 101 Pack, 36 Inch, Matte Black

Aluminum stair balusters deliver rust-resistant, low-maintenance support for safer stairs, decks, and porch railings. This 101-pack of matte black round tube spindles is built for indoor or outdoor use, with thickened aluminum tubing that resists corrosion and deformation. Hollow construction keeps handling easier during installs, while included rail caps and screws help you complete a clean, consistent railing line with fewer extra trips for hardware.

Upgrade tired spindles or finish a new build with round metal spindles made to handle weather exposure without constant upkeep. The consistent diameter and length help speed layout and keep your railing line visually even from top to bottom. Use them on staircases, deck perimeters, porch steps, or patio rails for a cohesive, modern finish. If you’re planning a full run and want enough pieces for matching sections, grab yours today and keep your project moving.
