How to install cable barrier?

Cable number:

During installation, determine the number of cables according to different applications firstly. Three of four cables are commonly used. Generally, more cables, the higher ability to redirect the errant vehicles.

Space distance:

The barrier post often installed with spacing from 6.3 to 32.6 ft. The thing you must to chew on is that longer spacing normally means the higher deflection distance.


Cables are fixed on the post and tightened to specific tension in accordance with the local temperature and environment. After tensioning, the reflection will be reduces and the ability to preventing vehicles from skidding off the road can be enhanced. Normally the tensions values range approximately from 2,000lb to 9,000lb.
