|---|---|---|---|---|
| BL434 | 12.70 | 3x4 | 43.7 | |
| BL534 | 15.875 | 3x4 | 66.7 | |

BL series per ISO 4347 / ANSI/ASME B29.8. Tensile values are typical manufacturer minimums for the listed lacing; the applicable standard minimum depends on series and lacing — request the factory data sheet for your exact series before ordering. Tensile is breaking load, not working load.
Selection limits: confirm working load (with safety factor), chain speed, temperature range and lubrication against your application before ordering. Tensile figures are minimum ultimate values, not working loads.
