Aluminum Post Sleeves

Westbury aluminum post sleeves are designed to fit securely over standard treated 4x4 or 6x6 posts, giving your deck or porch a clean, finished look. Available in two styles—Plain or Deco—you can choose between a smooth, heavy-walled sleeve for maximum strength or a decorative fluted option that combines style with added rigidity at a lower cost.

• Style Options – Choose Plain for a sleek, solid look or Deco for fluted detailing that enhances aesthetics.
• Sized for Railings – Offered in 37" and 47" lengths to match 36" and 42" Westbury aluminum railing heights.
• Flexible Installation – Works over new or existing 4x4 or 6x6 posts and porch posts.
• Extended Lengths – 8.5' and 9' sleeves available for taller posts or unique applications.
• Load Bearing Strength – Rated to hold up to 17,738 lbs, making them suitable as stand-alone porch posts.
