A deck can be the center piece of your home's outdoor space. Our 4x4 post caps will add a decorative element that enhances the architectural appeal of your home and the landscape. These cedar color flat top 4x4 post caps are made of ASA resin. It is a hard plastic that is known for its strength and durability. It is also UV and impact resistant. We chose to name this post cap cedar color as a way of distinguishing its redder hue from brown, which is a darker shade of brown. All of our caps will work for either a fence or deck, but we feel that the flat top is an excellent solution for outdoor entertaining and works exceptionally well on deck posts and railings.

Impact-Resistant Materials

Atlanta Post Caps offer various material options to create a unique landscape in your outdoor space. The patented ASA resin SNAP-Cap is the most preferred choice due to its UV and impact-resisting properties.

The material is commonly used in marine and automobile manufacturing due to its superior strength. ASA resin outlasts wood and offers protection from harsh weather conditions.

Another popular option are metal post caps. These post caps do not split or rot like wood. Despite a simpler silhouette, heavy-duty metal lets you create a custom style with powder coating or unfinished aluminum. These caps last for years at a fraction of the cost compared to wood and add a timeless decorative facet to your fence

Aesthetic Value

For classic-styled deck and fence posts, nothing looks better than black pyramid deck post caps.  Due to the pointed topper of pyramid caps, birds and squirrels will stay away from your fences keeping the area clean and requiring less maintenance.

Easy Installation

The patented Snap-Cap system makes Atlanta post caps easy to install without professional assistance. The two-part design of patented slim profile SNAP-Cap fence post caps includes a top piece and a sleeve that slides down about 1.5 inches on the post. The widest point on the cap will be approximately 5 inches after installation.

Unlike wood, ASA resin doesn’t shrink and expand with humidity fluctuations, and it won’t weaken because of the continual atmospheric and moisture changes throughout the year. ASA resin requires no maintenance, and that will never be the case with wood post caps. And one of the greatest benefits of our plastic post caps is that we’re selling you a superior product line for a fraction of the cost of comparable wood fence post caps. And they’ll last far longer, too.
