 Note About Ordering These along with Custom Cables

It is typically not possible to pass a cable through these grommets which has been terminated on both ends.  Rather, one end of the cable must not be terminated allowing the cable to be passed through it.  Only then can the other end be terminated.  If you’re ordering these to be used with custom cables which you’re also ordering from us, this is how to do so:

  1.   If you are using the Custom Cable Builder, select none for the Eyelet Style, Right.
  2.  If you are using the Custom Cable Builder 2.0, Select No Right End for the right cable end.

We’ll build such cables for you with no termination on one end so that they can be run through the grommets.  You’ll also need to purchase the part you desire and terminate and heat shrink it after the cable has been passed through the grommet.  Visit the Individual Components section of our website to purchase those parts separately.
