How to measure a Rubber Band
Rubber Bands are measured by 3 dimensions:
1) Diameter (Dia)
A straight line passing from side to side through the center of the band.
2) Width (cut width - CW )
The width of the band measures how wide the band is, vertical to the length.
3) Thickness (T)
The thickness measures the wall of the band.
Thickness commonly ranges from 1.1 - 2.5 mm.
