I used these to secure the header wrap around my Harley's exhaust pipes. Very easy to use if you've ever used a zip tie before! Just thread the skinny end through the clasp, use a pair of pliers to pull through TIGHTLY and done!

I used them on the wrap job two years ago, no sliding, no loosening. Just as good as day one!

You don't need an engineering degree to get the job done without instructions! Just a little common sense and know-how.
