What are the dimensions of a Trex picket?
The nominal dimensions for Trex pickets are as follows (*the difference between nominal and actual measurements is explained below):
- 67" (For Seclusions: used as vertical pickets for 6' tall Seclusions fence panels; can be used for 6' wide on center as bottom rail covers / For Horizons: used as horizontal pickets for 6' wide on center (actual width of a Horizons fence panel is one inch wider than Seclusions))
- 91" (used as vertical pickets for 8' tall Seclusions fence panels and bottom rail covers for 8' wide on center for any fence height / For Horizons: used as horizontal pickets for 8' wide on center (actual width of a Horizons fence panel is one inch wider than Seclusions))
Nominal vs Actual --
It is important to understand that within the construction industry, it is commonly understood that the same lumber components may vary in length, width, or even thickness based on the manufacturing process. What this means is that even if a component is labeled with certain dimensions - or nominal dimensions (let's take a 2x4 for example) - the actual dimensions may be slightly different (a standard 2x4 is closer to 1 1/2 x 3 1/2). That being said, the actual lengths of the Trex composite components - including pickets - may vary from the nominal lengths. This is due to expansion and contraction of the material during production. To compensate for possible variation in length, Trex overruns a component before cutting it during the extrusion process. That may add to the length or width of the component by as much as 2", although the typical overrun is less than an inch.
Keeping in mind that Trex pickets may vary from the nominal lengths, it is important to measure your material when you receive it and make any necessary adjustments or cuts to ensure a successful installation.
