Replacement Caps for Discontinued Trex Fencing Posts
These details will guide you through the process or ordering post caps if you are adding/replacing caps or filing a warranty claim for discontinued Trex Fencing post caps.
First, determine if the caps are the discontinued profile. The outer dimensions of Trex Fencing posts manufactured prior to 2010 are 5-1/2” x 5-1/2”. 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 caps currently in production will only fit the 5” post. If post caps are needed for the discontinued posts, the current 5×5 caps can be used in combination with an 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 and leveled to allow 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.
