Read the full review
The CALU LUKY pack holds 10 AF-100 replacement spools and 2 caps, each spool wound with 30 ft of 0.065-inch line. The listing states factory-wound line for feed, an ABS spool and polyamide nylon thread, and the same broad AF-100 model fit as the Generep pack. It also advises eye protection and long pants during use.
Pros
- Largest spool count here at 10 spools

- Factory-wound line, per the listing, for feed
- ABS spool and polyamide nylon thread stated
Cons
- No warranty term is stated on the listing
- No spring is stated in the pack
- Heaviest pack weight here at 15.8 ounces
- Title counts caps toward a 12-pack total, so the spool count is 10, not 12

Who it's for: owners of an AF-100 trimmer who mow light grass and want a tool-free spool change.
Who should skip it: anyone clearing strong weeds, or anyone who wants printed instructions in the box.
Read the full review
The Hechuang spool is a single AF-100 replacement wound with 30 ft of 0.065-inch polyamide nylon line. The listing states it snaps into place without tools, and that machine cutting and automatic winding save time over manual winding. It names a broad fit list, including GH, LST, CST, NST and LCC models. The listing also states plainly that this refill suits young grasses only, and that strong weeds call for other tools.
Pros
- Snaps into place without tools, per the listing
- Polyamide nylon thread stated in the listing
- Automatic winding, per the listing, saves time over manual winding
- Broad model fit list, including LCC models
Cons
- No warranty term is stated on the listing

Who it's for: owners of the GH models named in the listing who want a dual-line spool with a long length.
Who should skip it: anyone with an AF-100 trimmer, since this spool fits a different set of models.
Read the full review
The DF-065 is the only dual-line spool here, and it carries the longest length in the group at 40 ft of 0.065-inch line. The listing designs it for use with GH700 and GH750 trimmers, and names GH1000, GH1100 and GH2000 as compatible as well. Its power source type is stated as manual, so it differs from the auto-feed AF-100 spools above.
Pros
- Longest line length here at 40 ft
- Dual-line design, per the listing
- Brand spool from BLACK+DECKER
- Compact stated package size of 1 x 1 x 1 inches
Cons
- Narrow fit list next to the AF-100 packs
- No cap or spring is stated in the pack
- No warranty term is stated on the listing
- Manual type stated, not auto-feed
BLACK+DECKER RS136 0.065-Inch 20 ft Trimmer Line
Brand replacement line with 20 ft of 0.065-inch line for CST500, CST800, GE600 and the ST series models named in the listing.
Who it's for: owners of the ST, CST or GE models named in the listing who need a light, single refill.
Who should skip it: anyone who wants a prewound spool, a cap or a spring, or a longer length per refill.
Read the full review
The RS136 is a brand line, not a spool pack: 20 ft of line in a single count, at a stated weight of 1.6 ounces. One contradiction needs noting. The title states 0.065-inch, while the spec table lists cutting width as 0.06 inches. Trusting the title and bullets over the spec table, this article treats the diameter as 0.065-inch. The listing names CST500, CST800, GE600 and a long run of ST models.
Pros
- Brand line from BLACK+DECKER
- Lowest stated weight here at 1.6 ounces
- Long ST, CST and GE model list stated
- Single-count pack for a one-time refill
Cons
- Lowest line length here at 20 ft
- Spec table lists cutting width as 0.06 inches, against a 0.065-inch title
- No spool, cap or spring is stated, line only
- No warranty term is stated on the listing

Buying guide: choosing trimmer line for a Black+Decker trimmer
Match the spool model first
Fit comes before length. Three picks here are AF-100 spools, with broad model lists covering the GH, LST, ST, CST and NST series. The DF-065 fits a narrower set around the GH700 and GH750, plus GH1000, GH1100 and GH2000. The RS136 fits CST500, CST800, GE600 and the ST models named in its listing. Check the model number on the trimmer housing against the listing before ordering.
Diameter and length
Every pick here is 0.065-inch line, per the titles, so diameter does not separate them. Length does: the AF-100 spools carry 30 ft each, the DF-065 carries 40 ft, and the RS136 carries 20 ft. A longer length means fewer refills across a season of edging.
Pack size and spares
The Generep pack pairs 6 spools with 1 cap and 1 spring, and the CALU LUKY pack pairs 10 spools with 2 caps. Caps and springs wear out too, so a pack that includes them saves a second order. The other three listings state no cap or spring, so keep the old ones if they still hold.
Light grass or heavy weeds
The Generep listing states its line easily cuts through grass and weeds, and the CALU LUKY listing states fast cutting with a longer lifetime for its line. The Hechuang listing is narrower: it states the spool suits young grasses only, and that strong weeds call for other tools.
Handling and storage
The CALU LUKY and Hechuang listings advise eye protection and long pants during use, and the Hechuang listing adds that the tool should be unplugged before changing, installing or removing accessories. Store spare spools where they stay dry and out of direct sun.
Wear eye and hearing protection, long pants and sturdy footwear, and keep bystanders well back while the line or blade spins. Clear stones and debris first, and stop the engine or remove the battery before clearing the head. Refuel only with the engine off and cool. See OSHA landscaping safety. Read our Safety Disclaimer.
Matching It to Your Property
- For a small lot with short edges, a single spool or a single-count line covers the season without a shelf of spares.
- For a property edged with fences, beds and trees, prewound AF-100 spools that snap in keep the work moving past each obstacle.
- For a long driveway edge or a wide boundary, the 40 ft dual-line spool stretches further between refills.
- For storage, keep spare spools, caps and springs together in one dry spot.
The Acre Score explained
The Acre Score weighs five factors: performance, build quality, value, safety and warranty. Performance covers stated cutting ability, build covers spool and line materials, value covers pack size against stated specs, safety covers stated safety features, and warranty covers a stated term. No pick here states a warranty term or a safety certification, so those two factors add nothing, and the ranking turns on length, pack size and fit.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Generep AF-100 6-Pack | 9.6 | 30 | 21 | 21 | n/a | 0 |
| CALU LUKY AF-100 10-Pack | 9.6 | 29 | 20 | 21 | n/a | 0 |
| Hechuang AF-100 Spool | 9.6 | 29 | 20 | 20 | n/a | 0 |
| BLACK+DECKER DF-065 | 9.6 | 28 | 20 | 20 | n/a | 0 |
| BLACK+DECKER RS136 | 9.5 | 27 | 19 | 19 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: mowing large lots
Which trimmer line fits a Black+Decker AF-100 trimmer?
The three AF-100 picks here: the Generep 6-pack, the CALU LUKY 10-pack and the Hechuang spool. All three state AF-100, AF-100-3ZP, AF-100-BKP and AF-100-2 as fitting spool models.
What diameter is the line in these picks?
All five picks are 0.065-inch line, per their titles. The RS136 spec table lists 0.06 inches, but its title states 0.065-inch, and this article follows the title.
How much line comes on each spool?
The AF-100 spools carry 30 ft each, the DF-065 carries 40 ft, and the RS136 carries 20 ft. Pack size differs separately: the Generep pack holds 6 spools and the CALU LUKY pack holds 10 spools.
Does any pick include a cap or a spring?
The Generep pack includes 1 cap and 1 spring with its 6 spools, and the CALU LUKY pack includes 2 caps with its 10 spools. The Hechuang, DF-065 and RS136 listings state no cap or spring.
Can one line handle heavy weeds?
Not every pick claims to. The Hechuang listing states its spool suits young grasses only, and that strong weeds call for other tools. The Generep listing states its line easily cuts through grass and weeds.
