Measuring Handrail

Start by measuring the length of handrail you will need for your first run. For end posts you will measure from the outside of the handrail bracket on the post. If your handrail will end on a corner post, you will have two handrail attached to that post.

For best results, you will want to have one handrail terminate on the outside edge of the post, and the other on the inside edge of the post. Make sure you’re aware of this when measuring.

For runs longer than 8ft 6” you will likely need to use multiple pieces of cable railing handrail. The handrails come in a set length of 8ft 6” and the end of the handrail must terminate on the end post.

In this case, you will need to measure to the center to the center of the post that the handrail will end on, giving enough room for another room for another handrail to be mount.

Once you know the location of you post cuts, put monsters tape on the handrail to guard the area and use a sharpie to mark your cut line .

Cutting Handrail

We recommend using a chop saw or skill saw to cut your handrail. Make sure to use a blade suitable for cutting aluminum and as always secure the handrail with clamps to keep it from jumping

Now line up the end caps with the opening in your handrail and using a rubber mallet or dead blow hammer gently tap it into place. Repeat this step on the other end of the handrail

Mounting the Handrail

Place the cut capped handrail on top of the handrail brackets making sure that it is in the desired position. Then, clamp the handrail to the outside handrail bracket on the first and last post in the run. If you are mounting to a corner post, attach the clamps to one end of the handrail bracket as shown

Pre-drill all holes using a 9/64” drill bit. Once the holes have been pre-drilled, use the provide mounting screws to attach the handrail,

Now move the clamps to the inside handrail bracket on the same posts. For corner posts, move the clamp to the other edge of the handrail bracket, as shown.

Pre-drill and attach the mounting screws in the same way that you just did. You’ve installed the first express handrail in your system!

We recommend working one handrail at a time rather than cutting all your handrail first. When you mount a handrail it will pull posts together to secure the system. If you cut all your handrail first, this will make your measurements inaccurate. If you interested in purchasing an aluminum cable deck railing system find more in our shop!
