Attaching Trex Posts to Walls and Pillars

November 12, 2015Edmund Rose

While most fence posts are set in the ground in concrete footings, sometimes posts need to be mounted on top of walls or attached to pillars. With Trex, it’s easy.

Attaching a Trex post to a brick pillar

Although a Trex post is strong enough to stand alone without internal supports, the fact that it is hollow allows it to act as a sleeve when the situation calls for it. This is a perfect solution when you want to put the fence on top of a concrete wall. Using a pipe embedded into the wall or a tower with a base that can be fastened to the wall, a Trex post can easy slide over the internal attachment to hide it and to secure the fence posts.

 

Instructions on how to attach the Trex posts with embedded pipe and towers are available in our technical center. Please note: there are multiple ways that posts can be mounted on top of walls. These are simply two of them. In all cases, you should evaluate whether your wall can support the weight of the fence and the lateral pressure from force such as wind. In the case of a wall that is too thin or too shallow, an embedded pipe could break out of the side of the wall if heavy winds push against the fence.

 

As we’ve pointed out in other posts, Trex is often used for perimeter fencing where the fence runs between brick pillars or other types masonry columns. If the desired effect is to attach the fencing directly to the pillars, one method is to rip a Trex post in half and use a 2×4 to mount it to the pillar. Here are instructions for this method. The same principle applies to an exterior wall where a post is to be attached to the side of a building or similar structure.
