Eyoloty AF-100 Trimmer Spools 30 ft 0.065" – 24 Spools + 6 Caps + 6 Springs, Pre-Wound Nylon Auto-Feed for Black & Decker

Eyoloty AF-100 replacement spools are pre-wound 0.065" trimmer lines designed to fit select Black & Decker string trimmers and deliver reliable, automatic centrifugal feed for quick lawn touch-ups.

This kit gives you 24 ready-to-install AF-100 spools plus 6 replacement caps and 6 springs so you can replace worn spools quickly without re-winding line. Each spool contains 30 feet of 0.065" nylon line made from an abrasion-resistant polyamide blend engineered for longer wear and consistent feed action. The set is made to be a straightforward, cost-effective way to keep compatible Black & Decker models working through a full season of light maintenance.

Which Black & Decker models will these AF-100 spools fit?

These spools are built to the AF-100 form factor and are compatible with many Black & Decker consumer trimmer models. Check your trimmer part number against the included compatibility list before purchasing.

• Common compatible models: GH900, GH912, GH600, GH400, LST522, LST220 series and similar AF-100-style heads.
• Also fits model families NST, LST, ST, MTC/MTE, CST and BESTA listed in product features.
• Includes replacement RC-100-P cap and spring for heads using that cover style.

How does the automatic feed work and why does that matter?

The spool uses centrifugal force to extend line while the head spins, so you avoid manual rewinding during routine trimming. That means faster spool changes and fewer interruptions while edging or clearing grass.

• Pre-wound spools engage with the trimmer head to advance line under normal RPMs.
• Automatic feed minimizes the need to stop and pull new line by hand.
• Replacement caps and springs help maintain reliable feed and protect the spool.

What are the material properties and performance expectations?

The line is an upgraded nylon polyamide composition selected for improved abrasion resistance and tensile strength, offering longer life compared with basic monofilament lines. It’s optimized for trimming softer grasses and general yard maintenance rather than cutting dense brush or saplings.

• Line diameter: 0.065 inches (approx. 1.65 mm) — suited for light-to-medium yardwork.
• Tensile strength exceeds typical consumer-grade lines for better wear resistance.
• Use on tender grass and lawn edge trimming; avoid heavy woody weeds or thick brush.

What comes in the kit and how do I install a replacement spool?

The box contains 24 AF-100 pre-wound spools, 6 RC-100-P replacement caps and 6 springs to rebuild or refresh multiple trimmer heads. Installation is straightforward: remove the old cap, replace spring and spool, then snap the new cap into place following your trimmer’s manual.

• Contents: 24 AF-100 spools, 6 RC-100-P caps, 6 replacement springs — total 36 pieces.
• Installation: power off and disconnect trimmer battery or spark plug, remove head cover, swap spring and spool, replace cap.
• Safety: always wear eye protection and long pants when trimming; this line is for tender grass only.

Who is this for: This Eyoloty AF-100 spool kit is aimed at homeowners and landscapers who use compatible Black & Decker string trimmers and want the convenience of pre-wound, automatic-feed spools. It’s ideal for regular lawn edge trimming, clearing overgrown turf, or keeping multiple trimmers stocked for seasonal maintenance. If you often need to replace worn spools or want a bulk supply with spare caps and springs, this kit saves time and reduces downtime between jobs.
