Create a strong, solid foundation for your Trex Signature Aluminum railing system with the Trex Signature Aluminum Joist Post. Installed via a Trex Fascia Mount Bracket (sold separately), the Trex Signature Aluminum Joist Post allows you to make the very most out of every inch of your outdoor space by attaching securely to the outer edge of your deck. With a slim but solid 2-1/2 inch by 2-1/2 inch post size, the Trex Signature Aluminum Post can support your metal deck railing system without taking away any attention from the finished image of your deck.The Trex Signature Aluminum Joist Post is offered in the premium Trex powder-coat finishes of Bronze, Charcoal Black and Classic White.

Trex Signature Aluminum Joist Posts include the post itself, a coordinating post skirt (not needed for fascia mounting), a coordinating post cap and (2) structural mounting bolts for swift installation time.

For any scratches or imperfections in your railing, use Trex Signature Touch Up Paint Pen.

Note: When used with Trex® Signature™ Aluminum railing, posts can be installed on the outside of the fascia when railing spans 5ft or less between posts
