SpiderWire DuraBraid

Diameter chart, reel capacity & backing guide

Original box and spool photographed on a retailer host. Package date and present stock continuity are not established.

This guide covers the photographed DuraBraid SDB30G-150 package: 30 lb Moss Green, .011 in / .28 mm and 150 yards. Its original spool label identifies SAP 1556099 and UPC 022021647286. This is an undated original-label reference, not a claim that every DuraBraid strength, color or later package has the same diameter.

Construction: Braided fishing line; Moss Green SDB30G-150 package
Listed strengths: 30 lb
Line type: Braid main line

Plan around the 30 lb package you have

Use this reference when your package matches SDB30G-150 and its printed size. A 150-yard spool can supply the whole braid section or leave a remainder, depending on reel capacity, backing and the reserve you need. The nominal strength is one part of the choice; check it against your rod, reel and intended fishing before filling.

Your line. Your reel.

Choosing your setup

Choosing your DuraBraid strength

The photographed package is rated 30 lb / 13.6 kg. Its physical size is printed separately as .011 in / .28 mm.

The adjacent 10 lb Test Dia phrase is a monofilament comparison, not a second braid strength and not the capacity measurement.

Only this 150-yard Moss Green package is covered. A larger spool or another DuraBraid strength needs its own matching diameter label.

The diameter is manufacturer-printed, not independently measured by ReelCalc. No comparative toughness or abrasion result is asserted.

Backing, working line & leaders

Match the original package

Check SDB30G-150, 30 lb and .28 mm together. The photographed spool also carries SAP 1556099 and UPC 022021647286.

Choose your working length

Allow for your longest cast, a fish taking line, trimming and retying. A 150-yard package does not require a 150-yard fill.

Secure the spool connection

Follow the reel maker's braid attachment instructions. Where needed, start with monofilament backing and place the connection below the braid used during a cast.

Check the finished fill

Wind evenly under appropriate tension and stop at the reel maker's specified clearance. Inspect the line and knots before use; a legible label does not establish the condition of stored line.

DuraBraid questions, answered

Does 10 lb Test Dia mean this is 10 lb braid?

No. The package identifies the braid as 30 lb. Its 10 lb Test Dia phrase compares its size with monofilament; .011 in / .28 mm is the separate physical diameter.

Can I use these diameters for a different DuraBraid spool?

Only if that spool has its own matching manufacturer label or specification. This guide is limited to SDB30G-150, 30 lb Moss Green and 150 yards.

Are these current-stock specifications?

The original photo is undated. Its identifiers also appear in the manufacturer US feed, but that does not establish the age, condition or uninterrupted formulation of a particular spool.

Will the entire 150-yard package fit?

That depends on usable reel capacity and any backing. Plan the braid section first, check the estimate and leave the reel maker's specified clearance.

Specifications & sources

Checked September 13, 2026. Numeric values and package identifiers were read directly from the original box and spool photos hosted on eBay. The saved manufacturer US feed independently lists SAP 1556099 with the same UPC, strength, length and color, but supplies no diameter. Seller-entered specifications and stock claims are not used.

Calculations use the catalog's listed inch diameters. Published inch and millimeter values may differ slightly because of rounding.
