Instructions / Assembly
EZ Post Installation with Separate Mounting Flange 
Ensure that you have a solid mounting surface for your EZ Post base fasteners.  Existing posts 
or the EZ Posts (sold separately), may be used with this system. If you are installing EZ Posts, 
refer to the steps and illustration below. 
IMPORTANT: The distance 
between posts should not exceed 
6 ft. when installed above ground 
level. Always refer to your local 
building department for building 
code clarification. 
Note: When 
installing the 
post base into 
ACQ lumber, 
use stainless 
steel bolts (not 
included)  
IMPORTANT: Install 
supporting lumber below 
composite/wood decking 
when surface mounting 
posts to a deck. Fasten 
the 4” bolts through the 
decking and supporting 
underside lumber with 
the provided tee nuts. 
1.  Layout posts uniformly or as desired across entire project. 
2.  Ensure spacing between posts does not exceed 6 ft. for 
elevated decks (or greater than local codes specify). 
3.  Starting at a corner post, attach post flange to deck/patio 
using appropriate fasteners provided with the EZ Post Kit. 
MAKE SURE TO USE ADDITIONAL LUMBER BLOCKING 
UNDER THE DECK TO SECURELY FASTEN THE FLANGE!!! 
In some instances, fully threaded lag screws may be 
necessary – but are not included. LAG SCREWS LOOSEN 
OVER TIME AND REQUIRE QUARTERLY SAFETY 
CHECKS. 
4.  Slide 3”x3” post over post flange and plum using level. 
5.  Drill ¼” hole front-to-back through the entire post and post 
flange coming out on the back side. IT IS IMPORTANT TO 
DRILL HOLES WITH POST LEVEL. 
6.  Drill 2
nd
 ¼” hole front-to-back. Start hole 1” above the first 
hole. The vertical hole pattern creates the best deflection 
strength. Note that hole patterns can be modified if 
necessary. 
7.  Fasten post to post flange with 3 ½” bolt, washer, and 
standard nut provided. Washers must be placed on both 
sides of the post. 
8.  After post is level and securely fastened, slide decorative 
base cover (optional and sold separately) over post covering 
the post flange. 
9.  Secure next post using same procedure. At this point you 
may size (cut) and install a railing section to verify your 
desired layout. Then continue to set the remainder of the 
posts. 
Post Mounts are installed with 
railing sections in STEP 5.
