| Sling Thickness | Tolerance |
|---|---|
| 1 PLY | +/- 1.5 inches + 1.5% of Sling Length |
| 2 PLY | +/- 2 inches + 2% of Sling Length |
| 3 & 4 PLY | +/- 3 inches + 3% of Sling Length |
* For web sling widths wider than 6”, add 1/2” to these values. For tighter tolerance or matched set lengths,consult the manufacturer.
Matched Set Length Tolerance – When multiple legs of a bridle sling are made, or when multiple slings are prescribed to be made within a Matched Set Tolerance, their length variance from their nominal length shall remain within a dimension equal to one-half of their corresponding Standard Length Tolerance Values listed.
Measurement Method – Web sling length is measured with the sling laid flat while being manually pulled taut.
