Wooden Fence Post Caps for Deck Post Cover

Most 4x6 fence posts actually have nominal dimensions of 3 1/2" by 5 1/2", which would be planed down to around 3 5/8” by 5 5/8". These black plastic fence post caps are designed to fit perfectly on fence posts with inside dimensions of 3 5/8" by 5 5/8" and an edge height of 1/2".

Crafted from thick, highly durable, and weatherproof plastic, our plastic post caps are UV and heat-resistant, impact-resistant, and waterproof. You can expect them to withstand fading, cracking, and other damage for years to come.

These matte black pyramid caps are specifically tailored for wood posts with an interior dimension of 4" x 4". They are carefully crafted to fit rough lumber posts measuring 4" x 4" and are not suitable for other post sizes.

To better understand post cap sizes, refer to our guide. The listed measurement on a post cap corresponds to the size of the rough lumber or undressed post it is designed for. For example, a 4" x 4" rough lumber or undressed post would require a cap designed for a post measuring 4" x 4".
