Tips

1. Ensure that your posts and handrails are properly installed before your start cable installation.
2. You might have to buy extra materials than expected in case some materials might not be reusable after operation mistakes.
3. The recommended post spacing between two wood posts is 4ft-6ft, no more than 6ft.
4. The dimension of the wood post should be greater than or equal to 4inch to prevent the two tensioners from hitting each other at the corner.
5. The overall height of the railing, which is the structure of post and handrail, should be equal or higher than 36″ to meet the residential building codes of most states. Please consult your local building offices for building codes and make sure the system complies with the codes.
6.  3″ cable spacing and 200 lbs tension on each cable line are recommended in order to pass the 4″ sphere test (required by some states). You can buy a tension gauge online or from local stores.
