Installation Guide
LEVEL RAIL POSTS INSTALLATION:
1. Measure and locate the position of the post(s) based on the project layout.
Note: If an over-the-post installation is desired, the post will need to be cut from 
the standard length to accomplish this. To determine this height, place the post in 
the desired locations to be installed, and mark for the bracket location as instructed 
in step 7. Then, mark a line 3/4” above the bracket location marks. This will be the 
location to cut the post and permit the top rail to be installed flush with the top of 
the post and allow a deck board to be installed over the top of the post
2. Install the post by attaching the aluminum mounting flange to the surface of the deck or 
balcony. 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 post. If necessary, use wood blocking 
as reinforcement underneath the decking where the posts are located. Post mounting 
fasteners should be able to secure into the joist or reinforcement braces, not just the decking 
itself. When installing MoistureShield Pro Rail Post on top of a wood surface, screws must be 
lagged into at least 3” of solid wood. Deck boards sized 5/4” or 1 1/2” do not provide sufficient 
material for a safe installation.
Note: When installing MoistureShield
®
 Pro Rail Post onto treated wood surface, install the provided ACQ pad (included 
in the post kit) between the post base and the treated surface. 
3. Position the post to the deck surface. Four 3/8” diameter mounting 
holes are provided on the mounting flange. Mark the mounting flange 
hole locations and remove the post. Drill the marked locations into 
the decking and reinforcement using the proper size drill required for 
the fasteners being used. Remount the post. Insert the appropriate 
fasteners to secure the mounting flange to the deck structure.
4. Finish by sliding the base trim to the bottom of the post to cover the mounting flange.
5. To install the post cap, set it in place on top of the post and strike with a rubber mallet to 
drive the post cap onto the post. Silicone or water based caulking may be used to secure the 
post cap and base trim. 
NOTE: Post and balusters packaged separately.
