MAKING YOUR CUTS: 
Measure twice, cut once! 
Take your time to measure carefully and mark your cut on your piece of top rail. If you are using the CityPost 
provided aluminum top rail, or any other type of metal top rail, we highly recommend making sure the cutting 
surface of your chop saw is clean of any excess materials prior to each and every cut. This will keep a nice surface 
finish of the metal and limit the need for touch up later. If you are installing a natural wood to the CityPost system 
we recommend using at least 1” thick hardwood for your top rail.  
Pro tip: when cutting metal top rail use a piece 
of painters tape to cover the desired cut to keep the blade from coming in direct contact with the surface finish 
of the top rail, this will also limit the amount of touch up that will be required later.
If the piece of top rail you are installing butts up against a wall, but sure to install the end cap (if applicable) prior 
to final top rail installation.
ATTACHING TOP RAIL TO THE CityPost Top Rail Bracket: 
(If you purchased aluminum top rail from CityPost, your kit came with a bag of 1” #12 self-tapping sheet metal screws for top 
rail installation. If you procured your own top rail locally you will need to select a screw length that is appropriate for the top 
rail you selected. CityPost recommends using at least #10 screws for top rail installation). 
Set the cut piece of top rail onto the posts being sure to center the CityPost top rail bracket underneath the top 
rail. (Note: If you need to make an in-line joint due to a long run situation, butt the top rail pieces up to one 
another before installing the sleeve. They DO NOT need to be centered over a post.) Next you’ll want to take one 
of your top rail screws and secure (1) corner on each of the CityPost top rail brackets (leaving 3 empty). Once you 
have a single screw securing the top rail bracket to the top rail we recommend lifting up the section of top rail and 
place it upside down onto a non-abrasive surface to have unfettered access to the other (3) mounting holes in the 
top rail.  
Pro tip: while pre-drilling holes in the CityPost provided aluminum top rail is not required, using a 1/8” 
drill bit can speed up this process. When installing natural wood top rail, pre-drilling holes is recommended to 
ensure no splitting of the top rail occurs.
ATTACHING TOP RAIL TO THE POSTS:
Once you have all of the CityPost top rail brackets 
secured to the top rail you will carefully pick up the 
top rail, flip it back over and insert the top rail 
brackets back into the posts. Using a 1/8” drill-bit 
we recommend pre-drilling a hole into the top rail 
bracket through the mounting holes at the top of the 
posts. Lastly, you will take the bag of top rail bracket 
screws provided in your kit and secure the top rail 
brackets to the posts. 
STEP 2: COMPLETE! 
STEP 3: INSTALL & TIGHTEN CABLES
Let’s recap: At this point all of your posts should be installed and your top rail attached securely. If this statement 
is true, then you’re ready for the final step, cable! 
We recommend starting with your shortest horizontal segment of railing (if you have one) to get the hang of 
the process. Although it’s very simple, it does take a few tries to really master it, for this reason every kit 
comes with several extra end fittings. Just in case.  
PLEASE NOTE: THIS PROCESS IS TO BE FOLLOWED FOR EACH CABLE ONE AT A TIME 
INSTALLING CABLE THROUGH POSTS: 
Start by taking the spool of cable that you received in your kit and cutting off the zip ties to loosen the cable. 
Pro 
tip: if you place the spool in a 5-gallon bucket it will help to keep the spool under control while you’re working.
1. Determine the railing run that you are going to be installing cable into
