HOOTO AF-100 replacement spool kit includes 16 pre-wound 30-foot, 0.065" trimmer-line spools plus 3 caps and 3 springs designed to fit Black & Decker AF-100 series heads for fast, fuss-free mowing.

Keep your Black & Decker string trimmer running without downtime by swapping in ready-to-install spools from HOOTO. Each spool arrives pre-wound and cut by CNC machinery to the proper length and diameter so you skip manual winding and get back to edging and trimming sooner. The set is built to pair with a wide range of Black & Decker models and includes extra caps and springs so you have the small parts that commonly wear or get lost.

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

These spools are engineered to be compatible with Black & Decker AF-100-style heads and many model families that use the same spool form factor. Check your trimmer manual or existing spool label to confirm AF-100 compatibility before ordering.

• Fits AF-100, AF-100-3ZP, AF-100-BKP and related Black & Decker spool heads
• Compatible with models such as GH400, GH500, GH600, GH610, GH900 and many LST/NST/ST series
• Often identified as GH900, LST220, LST400 or AF-100 replacement spools on original parts lists

How are these spools prepared and why is that helpful?

HOOTO spools come pre-wound with 30 feet of 0.065" nylon line, cut and wound by CNC equipment for consistent tension and length. Pre-wound spools remove the guesswork and time of manual winding and reduce the risk of improper feed or tangles when you install them.

• 30 ft of 0.065" high-strength nylon line per spool for continuous trimming
• CNC-cut and wound for uniform performance and easier installation
• Pre-wound design minimizes downtime and eliminates manual winding errors

What parts are included and what if a cap or spring fails?

The kit supplies more than just line: it contains spare caps and springs to replace common wear items so you won’t be held up by a missing small part. Keep the extras on hand to maintain consistent spool retention and feed behavior over multiple refills.

• 16 replacement spools — enough for many seasons of light to moderate trimming
• 3 replacement spool caps to secure the spool in the trimmer head
• 3 replacement springs to ensure proper tension and line feed function

What trimming jobs are these spools best suited for?

The 0.065" diameter line balances lightness and durability, making it ideal for lawns, edging and clearing thin to medium weeds. For very thick brush or dense woody weeds, use a blade or heavier line as this nylon is optimized for typical yard maintenance rather than heavy-duty clearing.

• Best for grass, lawn edges, and light-to-medium weeds
• Not recommended as a substitute for metal blades on heavy or woody growth
• Good choice for quick spool swaps and routine yard upkeep

Who is this for: Gardeners, homeowners and landscape pros who own a Black & Decker AF-100-compatible trimmer and want a no-fuss supply of factory-sized replacement spools. This HOOTO kit suits anyone who prefers pre-wound cartridges to save time, needs spare caps and springs, or wants a bulk supply for regular maintenance. If your trimming tasks include thick brush or frequent heavy-duty cutting, pair these spools with proper cutting tools or heavier line as required.
