Strike King Contra Braid
Diameter chart, reel capacity & backing guide
This guide covers the original Contra Braid package labeled 20 lb, Green, 150 yd. Its printed .009-inch / .22-mm diameter provides a specific basis for capacity planning without applying one package's specifications to the rest of the Contra range.

Is this Contra package suitable for your reel?
Choose 20 lb only when it suits the rod, lure and cover. Then compare the intended working length with your reel's estimated capacity. A 150-yard package may cover a working section over backing even when it will not provide a complete braid fill.
How much Contra Braid will fit?
Calculated estimates, not measured fills. Stop at the reel manufacturer's fill level even if some line remains.
Strike King Contra Braid diameter chart
Original label prints .009 inch / .22 mm. Only this package is included; larger lengths and other strengths remain outside the verified scope.
| Strength | Inches | mm | Spools (yd) |
|---|---|---|---|
| 0.009 | 0.220 | 150 |
Choosing your Contra Braid strength
The large 20 LB mark is the line-test label. Do not enter the smaller trailing 6 LB mark as the braid's test strength.
Only the Green 20 lb package was verified here. Other Contra Braid strengths need their own diameter evidence.
Contra Fluorocarbon and Contra Monofilament are separate materials. Their packages and capacities should not be substituted for this braided line.
Specification-based planning guidance, not a hands-on Contra performance test.

Backing, working line & leaders
Plan within 150 yards
Allow for attachment, the longest cast, fish runs and future trimming before deciding how much braid to put over backing.
Secure the supply spool
The photographed package includes a Sidewinder tool. Follow its package directions to hold the supply spool while winding, and use steady tension.
Stop at the reel's fill level
Capacity is an estimate. Follow the reel manufacturer's arbor-attachment and fill instructions rather than forcing the entire retail package onto a full spool.
How Much Fits on These Reels?
Estimated full-spool capacity for the Contra Braid strength selected above, with no backing. These are calculated examples, not physical tests or recommendations for every pairing.

Contra Braid questions, answered
Does this verify every Contra Braid strength?
No. The numeric evidence is the photographed 20 lb Green label. Other strengths are excluded from this source-scoped guide.
Is the verified package 150 or 300 yards?
150 yards. Historical catalogs contain a 330-yard size alongside LPB300 model numbers; that larger-package discrepancy is not resolved here.
Can I use the fluorocarbon Contra chart?
No. Contra is a family name shared by different materials. Use the braid package's own diameter for a braid capacity estimate.
Specifications & sources
Numeric evidence comes from the readable original package label, not retailer-authored specifications. The manufacturer 2022 catalog verifies LPB150-20G identity. No current stock or package-revision equivalence is implied.
Calculations use the catalog's listed inch diameters. Published inch and millimeter values may differ slightly because of rounding.
