Replacement Caps For Larger Discontinued Trex Fencing Posts

5x5 Post caps for Trex composite posts

Replacement Caps for Discontinued Trex Fencing Posts

If you find that the our current post caps are too small for your existing post, you might have discontinued Trex Fencing posts.

Trex Fencing posts manufactured prior to 2010 have 5-1/2” x 5-1/2” outer dimensions. This profile was discontinued in 2009 and replaced with a 5” x 5” post. The post caps used for the larger post also were discontinued and the new caps will only fit the 5” post. If post caps are needed for the discontinued posts, the current 5×5 caps can be used with an internal plug (adaptor) that is set inside the cavity of the post and is attached with finish nails or screws.  The tops of the posts will need to be cut down to allow and leveled for the bottom of the posts caps to sit at 2-3” above the top of the top rail.

Because the old post caps covered up a portion of the top of the old posts, it is likely the color underneath has not faded and dirt and grime may have accumulated. Much of that will be cut off when the old caps are removed, but you may need to clean the newly exposed portion of the existing post. The new post caps will require time to weather to look similar to the older Trex material.

Caps are still available in flat top and pyramid styles. Trex Fencing – FDS Fence Distributors is the supplier for the post caps and adaptors. Contact FDS at 877-700-8739 or FDS@TrexFencing.com.
