Installation Guide
Prior to construction, check with your local regulatory agency for special 
code requirements in your area. Common railing height is 36" or 42". 
Read instructions completely to get an understanding of how the product goes 
together and how each piece affects the other.
Step 1 Determine the number of railing posts needed for your deck. Post 
spacing is 6'
 or 8' on-center. Example: A 12x16 deck attached to a building with 
a 4' access opening on one side will require a total of eight posts.
Step 2 Installing posts: Install posts by attaching the aluminum base to 
the surface of the deck. Position the post so the fastener will go into the floor 
joist, and make sure the decking is firmly attached to the joist at the location 
of the posts. If necessary, use wood blocking as reinforcement underneath 
the decking where the posts are located. Fasteners that hold the post base 
to the surface should be able to secure to joist or reinforcement braces, not 
just the decking itself. Note: When installing aluminum post on top of a wood 
surface, screws must be lagged into at least 3" of solid wood. 5/4" or 1 ½" deck 
boards do not provide sufficient material for a safe installation. If necessary, add 
additional material to the underside of the surface.
Step 3 Position the post assembly onto the location where it will attached 
to the deck. Four 11/32" diameter mounting holes are provided on the base. 
When the final position is determined, mark the base hole locations. Remove 
the post assembly and drill 15/64" holes in the marked locations into the deck 
and reinforcement.
Step 4 Reposition the post assembly over the predrilled holes and insert the 
fasteners (not included). Recommended fasteners: 4 – 5/16" x 4" or longer 
stainless steel lag screws.
Step 5 Finish by sliding a post base trim (optional) over each post for a finished 
look. Note: Installing the post base trim prior to installing the bottom rail is 
recommended. However, the two-piece design does allow the installer to add 
the post base trim after the rail has been installed. To install, apply a thin line of 
clear exterior construction adhesive to the inside of the post trim where it will 
contact the post sleeve and snap into place around the base of the post sleeve.
Step 6 Install baluster connectors to top and bottom rail using pre-drilled 
holes. Do not over tighten. 
Step 7 Measure the distance between installed posts to determine the length
