For example: Hole to hole measurement = 22" Hole-to-hole measurement x . 8" = 17. 6" Add one inch. Cut length: 18. 6".

Use boiling water to heat it. Using a hot plate or other heat source, boil a large pot of water. Once the water has come to a boil, insert several straps. Reduce the heat so the water remains hot but not boiling. Allow the straps to stay in the water at least two minutes, although leaving them in longer will not hurt them. Use a heat gun. Move the heat gun around frequently; do not allow it to rest at one place. Thirty seconds of moving it around the strap and it should be heated enough to use.

If the rivet is difficult to insert, use a rubber mallet or hammer to tap it in.
