4 inch aluminum stair post kits anchor the heavy-duty corners and transitions on your deck stairs, and the Deckorators ALX Contemporary 4" Stair Post Kit brings that larger profile down the stair run. The 4" powder-coated aluminum post ships at extended stair heights with a welded base, 1-piece trim, and cap, so contractors and experienced DIYers can carry a stout anchor point through gates and corners on a stair section.
Features & Benefits
- Larger 4" profile adds strength for gate posts and corners on stair runs.
- Extended stair heights carry your railing down the stairs at the right pitch.
- Welded base lands solid on stair framing for a secure anchor.
- 1-piece base trim covers the base plate and fasteners for a finished look.
- Powder-coated aluminum resists scratches and corrosion, so the finish holds up outdoors.
