Diameter chart, reel capacity & backing guide
Grappler 8 is Shimano's multicolor eight-carrier braid for casting and jigging. Its New Zealand table reports average strength in pounds, including 24.7, 38.6 and 59.5 lb. Those exact labels and the 300-meter package are preserved here, without turning them into familiar round-number tests.
Consider Grappler 8 when you want a multicolor mainline for tracking line paid out during jigging or casting. Shimano specifies VT Construction and a heat-management coating. The specifications do not establish a guaranteed breaking load or measured casting advantage for a particular setup.
NZ Multi 300m set; exact manufacturer average-pound labels. Two conflicting low-end pound rows withheld. Published mm; inches and yards converted.
| Strength | Inches | mm | Spools (m / yd) |
|---|---|---|---|
| 24.7 lb | 0.006299 | 0.160 | 300 m (about 328.08 yd) |
| 30 lb | 0.00748 | 0.190 | 300 m (about 328.08 yd) |
| 38.6 lb | 0.007874 | 0.200 | 300 m (about 328.08 yd) |
| 59.5 lb | 0.009055 | 0.230 | 300 m (about 328.08 yd) |
| 73.6 lb | 0.011024 | 0.280 | 300 m (about 328.08 yd) |
| 99 lb | 0.01378 | 0.350 | 300 m (about 328.08 yd) |
| 134 lb | 0.016535 | 0.420 | 300 m (about 328.08 yd) |
The verified 30 lb row is .190 mm and the 38.6 lb row is .200 mm. The latter is not renamed 40 lb; its label is an average-strength specification.
The 59.5 lb entry is .230 mm and 73.6 lb is .280 mm. Use the published physical diameter for capacity, not a PE-size conversion.
The smallest two source rows have conflicting title/table pound figures, so they are withheld. The verified range starts at the coherent 24.7 lb row rather than concealing that discrepancy.
Specification-based guidance, not a hands-on Grappler 8 test. Capacity results are estimates, not measured fills.
Each verified SKU supplies 300 meters, approximately 328.08 yards. Keep the package identity in meters when ordering.
Current and drift can put more line out than the vertical depth suggests. Choose a working length that covers your fishing depth, line angle, runs and subsequent reties.
Choose terminal leader material and its connection independently. The short leader section is not the mainline used in the capacity calculation.
No. It is the manufacturer's explicit average-strength label. This guide does not rename it or reuse an old 40 lb row.
What does the Heat Sink coating prove?It is Shimano's stated heat-management treatment. It does not provide a measured temperature or durability guarantee for your fishing conditions.
Are these diameters calculated from PE size?No. Millimeter diameters are printed in the exact SKU table. Inches are conversions of those values.
Checked 2026-09-13. SKU table and lineup titles compared. Existing 20/40/50/65lb IDs are not relabelled. One PE3/2GOU title mismatch is recorded but no PE field is used.
Calculations use the catalog's listed inch diameters. Published inch and millimeter values may differ slightly because of rounding.
