A common trend of installing cables in new or existing wood posts continues. These cables enhance your room’s beauty and support wood posts. So, to upgrade a modern look and save time and money, you can look up cable installation. 

Many wood post kits are available in the market to support the process. You can quickly get the perfect one according to your choice and budget. Let’s settle down and look at how to fit cables in wooden post corners.  

Types Of Wood Posts 

Single Post 

Separated cables can’t run efficiently along the single post corners. So, you always need a line for a post. Now, select one set of wires and run them through one corner. After that, pick the second set of cables and push them to the other side of the corner. It would be best if you made an intersection inside the wood posts. 

That is why both the corners need to be pitched about 1/2inches. You can also produce a jig cut of about ½ inches. However, keep in mind that your jig cut needs to be shorter in height and should be enough in size to fit between the top rail and decking. 

This is how you can drill holes in the desired pitch. Once you are done with the fixes, you can push odd the threaded cable ends into every hole and protect the opening with a nut. 

So, when you notice everything is in place, you can cap up the nuts for a vibrant look. 

Double Post 

You can easily cover the single cable around each corner in double post corners without any need for offset or support. So, the lines will stick in place even when pushed around the corners once you are done with drilling. You can secure the sleeves in post. 

We need to do this because doing so will save the wood from getting damaged while pushing the post. Also, a threading needle can help you thread the cable along the holes by securing every cable strand. 

So, not a single cable strand will be stacked by the holes. Also, you can protect cables by reducing their tension using a terminal post. 

Material Required To Secure The Process 


5/32 inches diameter cable and 1 Tensioner kit
Post hole cover
Boeshield stainless steel liquid
Cable space bar kit and Shop rag


A ½ inches chuck drill
Drill bits 9/16 inches and 3/16 inches
Bullet installation kit including cable cutters
hex power bit, 3/32″
Allen key, a crimper, and bullet driver
Tape measure
Socket screwdriver, drill guide and socket wrench

Important Point To Be Kept In Mind 

1. You need to keep in mind that the cable tensioning posts can only be kept 10-20 feet apart. So, to uphold the tension, you need to add tensioners. This will help you for running tensioners for an extended period. 

2. After every 40-45 inches, you need to add cable spacer bars. These bars will help you to reduce the load over the system. 

3. Maintain deflection of the cable every 3-4 inches. This tip will help you maintain a constant gap among the cable runs. 

4. You must always hold up the top rails with structural posts. 

5. It is highly recommended to consult professional builders if you are a newbie. You can get some help in post spacings and rails design of the project. 

How To Install Cable Railing In Wood Posts 

Start-Up By Measuring And Marking The Posts 

The first and most crucial step is to start up by marking and measuring the post. Identify all the sides of the post. Now notice the space between each post. You need to grab up a marker and a painter’s tape. Now, tap the area vertically and mark the drill points. 

Similarly, in measuring the end and intermediate posts, you need to measure and mark every location. Also, keep in mind to measure the drill bit at every step to maintain the constant depth while drilling. Now, remove the tape. 

Making Holes 

Now, it’s time to drill the hole. You need to use a drill bit of 9/16 inches to level the gap. The depth of the hole should be about 1-1/2 inches. You can use a hardwood tap to install the hardwood posts easily. 

If you are working with post wraps, you can use a drill bit of 5/18 inches along post wrap to make the process easy.    

Pass From Holes 

You can take the help of a top-notch carbide bit of about 3/16 inches. You help you drill cable to pass from the holes. You can prepare deep and thick posts and columns to keep a constant balance between level holes. 

To make the drilling process easy, you can use a bullet drill guide to get help while working with the tensioner and the pass-through holes.   

Working With Tensioners 

Take help of the drill with about ½ inches chuck and the bullet driver. This combination will help the driver to drain bullets in the post. You can also take the help of a wrench or a head of 7/16 inches to arrange tensioners in the correct location. 

These tensioners will make the process easy and help you maintain the angle and pushing of the cables. However, you must remember if you use an impact driver for tensioners. You can damage the size of the channels. 

Covering Holes 

Once you are done with the drilling process, it’s time to cover the holes and secure the posts. So, you can use post hole covers along with the T-10x 2 inches star drive power bit. However, if you are working with a hardwood post, you can use a drill of 3/32 inches to make a hole and cover the post hole. 

The best way to cover up your post hole is to use a piece of cable and make it hung with the fix.   

Spacer Bars 

To combine the space bar to the top rails, you can take the help of standoff. All you need to do is drill a pilot hole of about 1/8 inches with the drill. This hole is made to support the standoff. Now, since the spacer bar. At last, hand the standoff into the spacer bar. You are all done. 

You can also take the help of the painter’s tape while making the standoff threads with the spacer bar. 

Getting Rid Of Over-Sized Cables 

Now, take the cable sizing and cut off the extra wires. Any rough cable length should not be present in your wood posts. However, it would help if you remembered that while cutting the cable, keep a few inches. These few inches are kept just in case so that you never run short of the thread. 

Greasing Up Tensioners 

To make the installation of the tensioners easy. You need to add up some drops of the greasing. You can use Boeshield Lubricant to drive the screw path of the tensioner once you notice that the greasing is applied. 

You will see a decrease in corrosion and seizing. Remember that you don’t have to spill the lubricant on the whole wood surface. 

Crimping The Cable 

You need to fit the ends of the cable with a lobed washer and a crimp sleeve. Take the help of the Cable Bullet crimper to crimp the wire quickly and efficiently. So, the crimper will take about 9-12 pumps. 

Setting The Ends 

For setting up the cable, you need to push the crimped cable and the washer. Now fit the crimped cable in the tensioner with the help of 3/32 inches Allen key. This key will help you lift the set screw to a new level. 

As for decreasing the risk of galling, you can take the help of a manual socket. 

Locking And Setting The Cables 

When you are done with the crimped ends of the cables, it’s time to thread your cable from the intermediate posts along with the spacer bars. Doing so will help you keep the wires in the wood rails for an extended time. 

Re-Cutting Cable 

At this point, you need to cut the cable in exact length. You remember that in the previous step, we extracted the cable keeping a few inches in our hands. You need to maintain a cable hand tight. So, measure up the inches keeping the tensioner in mind. 

Now, cut the cable at the exact length of the post. 

Ending Tensioning 

So, finally, when you are done with all the previous steps. It’s time to give a final call to the tensioning. Startup with the inner cable and begin tensioning outwards. Your line needs to have to tension of about ¼ inches per foot. You can judge tensioning of the wire by noticing that the wire should feel like guitar strings.   

Locking Spacer Bar 

The most essential and concluding step is to lock your floating cable. You need to lock it in the spacer bars such that no extra screw top or bottom comes forward. Here you are set with installing cable rails through wood posts. 

Final Conclusion 

Installing cables in wooden rails is not an easy process. However, if you do it rightly, you can keep your wooden fences upstanding for an extended period. Notice to do all the steps in a proper format. Also, you have to be very careful while doing the procedure. In case you are still confused about some actions.
