Tape rolls are cut to standard tape industry metric widths of approx. 24mm per 1-inch of nominal width ordered. As a result ACTUAL tape widths are normally5% narrower than the NOMINAL width shown in inches. Examples:
1" Nominal width = 15/16" (24mm) Actual width
2" Nominal width = 1-7/8" (48mm) Actual width
3" Nominal width = 2-13/16" (72mm) Actual width
Note that tape rolls are NOT guaranteed to be splice-free.
