Understanding the Importance of 4x4 Post Caps

Aesthetic Enhancement: Post caps add a finished look to your fence posts, decks, or other outdoor structures. They can complement your overall design style, adding a touch of elegance or rustic charm.
Structural Support: Certain post cap designs offer added structural reinforcement, preventing warping or splitting of the post's top.
