How to install a CR side mount post kit on the side of a deck or floor — this one guide covers BOTH the side mount PLAIN post and the side mount CABLE post, because the post kit and its mounting procedure are the same hardware.

Read every message in this section before you touch any component. They apply to every model this guide covers and to every installation surface.
Please make sure the hardware and tools we provided will be right for your install (read the means & methods disclaimer). IT IS POSSIBLE YOU NEED DIFFERENT HARDWARE & METHODS.
Please take your time to do your installation. If you are unsure or uncomfortable with the installation, we highly recommend hiring a licensed and bonded contractor.
The strength of the anchor is dependent on the hole size & concrete integrity. A hole that’s too big, or concrete that’s not up to standard grade, can make the anchor wiggle or possibly come out. This is what can cause a rail to fail & fall over.
The recommended distance between posts is 3 to 4 feet, with 4 feet as the maximum. Our cable posts have holes drilled 3 1/8" centre-to-centre. For compliance with the 4-inch sphere test standard, maintain this spacing AND apply 200 lbs of tension on each cable. Tension gauges are available online and at local retailers.
Our cable sleeve protectors fit standard 1/8-inch cables. Aftermarket stainless steel protectors may need larger holes drilled — check size compatibility with our post design before you drill. End slip-in terminals are an option. If you have already drilled larger holes by accident, contact customer service for a full refund.
In no event shall CR Fence & Rail Inc have any responsibility, control over, charge of, responsibility, or liability for the means, methods, techniques, sequences, or procedures, or for safety precautions in connection with the installation of the railing, since these are solely CM/GC’s, Subcontractor’s, and Owner’s responsibilities.
Each installation site differs widely ranging from the construction & condition of attachment points, local building & safety code, local construction code, and local means & methods.
CR Fence & Rail Inc’s installation guide (whether it be in text, illustration, video or in support discussion) constitute for ideal installation condition. There is no ideal installation in real life. There is no substitution for consulting a local licensed contractor, architect, engineer, nor code inspector.
CR Fence & Rail Inc’s installation hardware and tools are provided as building material and does NOT constitute as the specific nor final installation hardware. Once again, you and your installer must make the final on-site determination to the specific means and methods of installation appropriate for your installation.
Following CR Fence & Rail Inc’s instruction does NOT constitute as proper installation as you and your installer must make the final means & method determination. Improper installation can lead to failure of rail system which can cause serious injury or death.

This will be a tight fit. In fact, the specification calls for the drill bit and anchors to be the same size. Some installers use a 3/8" drill bit to make the installation easier, and other installers wiggle the drill bit to bore the top of the hole slightly bigger. We are aware of the tight fit and we only recommend using our masonry drill bit without wiggling.
Mark the location for the first post. Measure a maximum of 4 feet to the second post, continuing for additional posts. Ensure the markings are from the CENTRE of one post to the CENTRE of the next.
2 Position the metal plate on the side flooring and mark the hole locations with the provided pencil.
FOR WOOD — use the wood pilot-hole bit (the smaller bit). FOR CONCRETE — use the masonry drill bit (the larger bit). Using an electric drill, drill pilot holes following the marked points.
3 Use the pencil’s flat end to check the depth of the holes, ensuring they are deep enough for the anchors. Hole NOT deep enough: keep drilling deeper. Hole TOO DEEP: be careful not to insert the anchor too deep.
4 Once the holes are made and the depth is verified, hammer the anchors into the holes. Then place the post on the anchor and ensure the nut has enough thread for secure tightening.
To avoid pushing the anchor too deep, stack two washers and two nuts at the end of each anchor before hammering.
5 Line up the metal plate with the pre-drilled holes in the post. Secure it using flat-end screws in the second and third holes.
If your side flooring does not have an edge lip, you can skip this step.
6 Use the nut socket and bit extension.
FOR WOOD — align the post with the drilled holes in the side floor, then insert and screw the lag screws through the post and into the side floor using an electric drill with the bit extender and nut socket.
FOR CONCRETE — remove the nut and washer from the anchor bolt, position the post so the base plate holes align with the anchor bolts, then attach the nut and washer for each bolt and tighten with an electric drill using the bit extender and nut socket.
Make sure the anchors and screws go through the metal plate AND into the side flooring securely.

7 Plug the holes with the provided hole cover — it should snap in place, no adhesives needed. If you are not installing a top rail, attach the post cap to seal the top of the post, then place the bottom end cap at the bottom of the post.

The top rail is sold separately.
8.1Install the top rail bracket onto the post with the top of the bracket flush with the top of the post. Make sure the hole is facing inwards, or towards the second post. Secure the bracket to the post using 1 self-drill screw per bracket.
This post can be used with a top rail and middle rail, or with a baluster guard rail and top rail.
8.2Attach the top rail bracket to the post and secure it using 2 self-drill screws per bracket. When attaching the bracket, ensure the flat top post does not stick out, to allow proper placement of the top rail.
Top rail connectors join one CR rail kit to the next, turn a corner, or close a run against a wall. They are fittings used inside the installation above, not a separate job.
Fit the connector before you secure the joint: seat both rails fully into the connector, then drive the self-drilling screws through the pre-made holes. Use 2 screws on each end of a top rail connector, on the bottom side.

The legacy instruction-guides page served this same file under two headings — "Side Mount Plain Posts" and "Side Mount Cable Rail Post" — which is CORRECT: it is one post kit. This page says so, which the legacy page never did.
