YWNYT SF-080 Replacement Spool for Black and Decker GH3000/LST540 Series - 20ft 0.080-in Auto Feed Spool (12 Pack)

Upgrade your trimming kit with the YWNYT SF-080 replacement spools

Designed for compatibility with popular Black and Decker models such as GH3000, GH3000R, LST540, and LST540B, the SF-080 spool set offers a straightforward replacement option when your old spools wear out. The spool itself is crafted from a sturdy ABS material, paired with a durable polyamide nylon line that stands up to routine yard work. Each spool carries a 20-foot strand of line with a 0.080-inch diameter, ready to snap into place and resume trimming with minimal downtime.

What makes these spools stand out is how the line is engineered to work with the trimmer’s dynamics. The combination of centrifugal action and aerodynamic design helps reduce drag, which can translate into a steadier feed and quicker cuts through light growth. This design is built to pair with common auto-feed systems, creating a smooth line advance during use.

What you get

• 12 replacement spools per pack, compatible with Black and Decker models
• Each spool pre-loaded with 20 feet of 0.080-inch nylon line
• ABS spool with a durable nylon line, designed for flexible and long service life

Usage tips and safety

• Wear safety goggles and long pants to protect against loose line debris
• Unplug the tool before changing or installing spools
• Best for light to moderate grasses and weeds; very tough growth may require other tools

Installation is straightforward on supported Black and Decker models. While the SF-080 is a standard replacement option, always verify model compatibility in your manual and follow the tool’s safety guidelines during a spool change. Keeping a spare pack on hand can help you swap spools quickly after a trimming session, reducing downtime and helping you maintain a tidy outdoor space.

Performance and longevity

The combination of ABS resilience and nylon line offers a balanced option for regular trimming tasks. The 0.080-inch line provides strength and precision for edging along sidewalks and fence lines, while the 20-foot length minimizes reloads for longer projects. The design aims to deliver reliable line advancement without excessive wear on the spool housing.
