General Purpose Structural Post with Angle Adjustment by LMT Mercer

Create a solid foundation for your deck railing with these Structural Posts made of rugged galvanized steel, which eliminate the time, effort and expense associated with installing traditional 4 inch x 4 inch wood posts. Each structural post is made of sturdy 1/8 inch thick steel and has a mounting plate for quick installation on wood or concrete (fasteners not included). The bottom PVC guide block should be centered at the height where rail brackets will attach to the post (secure with the included 1 inch screw). The top PVC guide block has complete adjustability to ensure the post is plumb (loosen the center nut to adjust). Slide your choice of post sleeve over the structural post and the rail brackets will make a secure connection through the post sleeve and into the PVC guide blocks.

Used as is, the post is perfect for 36 inch rail systems, or simply remove and flip over the top guide block to get extra height for a 42 inch rail system. Note that you will need a socket extension to tighten the nut.
