Product Overview

The SIEDiNLAR 4×4 post caps are engineered to give any outdoor structure a refined, uniform appearance while protecting the post material from the elements. Constructed from high‑grade matte‑finished ABS, each cap offers UV resistance, waterproof sealing, and a sleek black finish that complements both wood and vinyl posts.

Each package includes twelve caps, two pre‑drilled holes, and stainless‑steel screws, allowing for a tool‑free, glue‑free installation that holds up under rain, snow, sun, and wind.

FAQ

What post sizes are compatible with these caps?

The caps are designed for nominal 4×4 posts, which correspond to actual dimensions of 3.5″ x 3.5″ for wood and 4.05″ x 4.05″ for vinyl. They will not fit larger 4.5″ x 4.5″ or 5×5 posts.

Do I need any special tools to install the caps?

No special tools are required. The package includes stainless‑steel screws and a simple screwdriver is sufficient to secure each cap firmly in place.

How does the ABS material hold up against extreme weather?

ABS is highly resistant to UV radiation, temperature fluctuations, and moisture. The caps will not crack, fade, or warp even after prolonged exposure to sun, rain, snow, or wind.

Can I paint the caps to match a different color scheme?

While the caps are designed to look great in their matte black finish, they can be painted with a suitable exterior‑grade paint if a different color is desired. However, painting may affect the original UV‑resistant properties.

What is the warranty or return policy for these caps?
