Meet the Pyramid Aluminum Post Caps crafted for actual 3.5 x 3.5 wood posts. The matte black powder-coated finish pairs a sleek, contemporary look with rugged, long-lasting performance.

• Thoughtful safety touches include rounded edges for safer handling during installation and everyday use.
• Specific fitment for real 3.5 x 3.5 inch posts ensures a snug, secure appearance on standard 4x4 wood posts.

What you get and how installation works

• Complete PC44-4 pack includes four post caps and eight rustproof screws for quick setup.
• One-step installation — place the cap on the post and secure with the included screws using a drill; no complex tools required.

Real-world uses and longevity

Ideal for deck railings, fence lines, and patio enclosures, these caps combine weather resistance with a clean aesthetic. They’re designed to endure wind, rain, and sun while maintaining their finish and shape with a low maintenance profile. The product is backed by a long-term warranty, signaling confidence in its durability and quality. As outdoor materials age, these caps offer a ready-made upgrade that can refresh the look of any wooden post.

Note: While results can vary based on installation and environment, the combination of marine-grade aluminum, protective coating, and solid construction presents a practical option for enhancing post tops without altering the structural behavior of your posts.
