How do I know if my zip line is tight enough?

Cable tension is measured by cable Sag:

  • The Cable, when bearing a test weight, should sag below the end where cable is attached.

  • The sag needs to be approximately 2% of the Zip Line’s total length. (2’ Feet per 100’ feet of cable). 

  • The sag is measured at the cable’s lowest point.

  • If your sag measures 2%, your cable is tight enough. 


 !!Warning!! Do not attempt to ride your zip line without first testing.


Instructions for how to measure cable sag can be found in the Zip Line Gear handbook included with your purchase. You can also view a digital version of the “Cable Slope & Sag” section of the handbook right here.
