Black & Decker Trimmer Line Replacement Spool, Easy feed, Dual-Line, .08-Inch

A field test with the EFD-080 spool

I swapped my trimmer’s tired cartridge for the EFD-080 spool on the first warm weekend of the season and set out to see whether a simple consumable could make yard work smoother. It’s a small, inexpensive component, but on a push-button EasyFeed trimmer, the spool is the heart of the experience. With this dual-line, 0.080-inch prewound spool, Black & Decker promises clean feeding without bumping and a quick, no-fuss install. After several weeks of edging beds, knocking back fence-line grass, and tidying up a driveway, I have a clear sense of where it shines and where to be cautious.

Compatibility and fit

The EFD-080 spool is designed for Black & Decker’s EasyFeed trimmers, specifically the LST560C 60V MAX model. On that head, fit was exact: the spool dropped into the housing, keyed properly on the arbor, and the cap locked without drama. The dual-line design pairs with the trimmer’s guard cutter to set the correct length on first spin-up.

This isn’t a universal Black & Decker spool. The brand uses different bobbin geometries across its lineup, and some older or different-series models expect distinct spool cores or wind patterns. If your trimmer is not an EasyFeed unit—or the part guide doesn’t list EFD-080—don’t assume it will fit just because the diameter looks right. Matching the part number to your exact model is the safest way to avoid frustration.

Installation and setup

Installing the EFD-080 took under a minute:
- Pop the cap.
- Seat the spool with the arrows facing the correct direction.
- Clip each line into its retaining notch and thread through the eyelets.
- Snap the cap back on.

The prewound line was cleanly laid with even tension. There were no kinks or crossovers visible, which matters a lot for smooth feeding later. Because it’s dual-line, you get two equal-length strands out of the gate; the cutter on the guard trimmed the excess to the proper length within seconds of starting the trimmer.

Feeding performance

EasyFeed is push-button, not bump-feed. That means the trigger coil pulses the motor to advance line rather than relying on head impacts with the ground. With the EFD-080 spool, line advancement was consistent and predictable. A quick tap of the button delivered a small, repeatable increment—enough to compensate for wear without spitting out inches of waste.

I paid close attention to two common trouble points: false advances (where the line feeds when you don’t want it to) and stalls (no advance when you do). I didn’t experience either. One measured press advanced both strands evenly, and the trimmer’s cutter kept each side the same length. If you’re coming from a bump-feed head, the push-button system feels almost low-drama: less downtime fiddling, fewer head strikes, and no guessing if the pawls caught.

One caveat: push-button systems make it easy to overfeed if you treat the button like a throttle. On edging passes, I got best results giving a very quick press only when I heard the cutting note drop—a sign the line has shortened. That minimized waste.

Cutting performance and line life

At 0.080-inch diameter, the line is well-suited to residential trimming: thicker than the light 0.065-in stuff that breaks on woody stems, but not so stout that it drags down a battery trimmer in tall grass. On the LST560C, the dual-line setup cut a nice swath with minimal fray. Grass, plantain, and fresh dandelion stems were cleanly sliced. The line nicked and wore faster on chain-link and paver edges—as expected for any round nylon—so I paced the edging work to avoid grinding the line against hard surfaces.

In terms of longevity, I averaged a couple of full yard sessions (front edging, rear fence line, garden perimeters) per spool before the lines neared the core. That will vary widely based on how much hardscape you edge and how aggressively you feed. The takeaway: for routine suburban maintenance, the 20 feet of prewound line feels reasonable. If you routinely tackle woody weeds or rub along stone, expect to consume spools faster.

Jams, welding, and general behavior

A poorly wound spool can cause line welding (heat fuses layers together) or create tangles that block feed. The EFD-080 I used didn’t jam or weld. After longer runs, the spool remained free-turning with no visible deformation. The line never fused to itself, which suggests the wind tension and line material are appropriate for EasyFeed’s stop-start pulses.

The spool housing itself is sturdy enough for repeated swaps. The flanges didn’t flex or crack under cap pressure, and the center boss shows no wear after multiple removals. It’s a small piece, but the tolerances here matter; slop translates to inconsistent feed. I didn’t see any.

Maintenance and rewinding

The point of buying a prewound spool is convenience: drop it in and get back to work. That said, if you want to save a few dollars by respooling yourself, this bobbin can be rewound with 0.080-in line. A few tips if you go that route:
- Follow the directional arrows on the core.
- Wind with steady tension and avoid overfilling; leave a small margin under the flange.
- If it’s a dual-channel core, split the line evenly between both sides to keep the feed balanced.
- Pre-stretch the line slightly to reduce springback.
- Lock each line into its notch before threading through the eyelets.

Do that correctly and you’ll preserve the jam-free behavior that the factory winding delivers. Do it poorly and you’ll chase tangles and uneven feed.

Noise, balance, and user experience

A smooth-feeding spool reduces both noise and vibration because you’re not whacking the ground to advance line or dealing with off-balance lengths. The EFD-080 kept the head balanced, and the cutting note stayed constant except when the line shortened with wear. Press, advance, trim—back to work. That rhythm becomes second nature after a few passes, and it keeps your attention on the cut rather than the tool.

Value and cost considerations

Prewound spools cost more per foot than bulk line, but they give you consistently tight winding and plug-and-play reliability. If your time is at a premium—or you’ve fought with jam-prone DIY winds—the EFD-080 makes a strong case for convenience. For high-volume trimming, buying a few spools ahead of the season is painless and keeps momentum on yard days.

Where value dips is if you’re using a spool that isn’t the precise match for your head. Misfits look similar but produce poor feed. Double-checking the part number against your trimmer model avoids returns and wasted time.

Who it’s for

• Owners of the LST560C 60V MAX EasyFeed trimmer who want predictable button-fed line with minimal setup.
• Homeowners working in mixed turf with occasional edging along concrete or pavers.
• Anyone who prefers a prewound, dual-line cartridge over hand-winding.

Not ideal for:
- Heavy brush clearing or stubborn woody stems where thicker or specialized line types (twisted, serrated) might be advantageous.
- Trimmers outside the EasyFeed family that require a different spool core or winding pattern.

The bottom line

The EFD-080 spool does the fundamental things right: it drops in cleanly, feeds on command, resists jams, and cuts well for its class. The dual-line, 0.080-in setup is a sweet spot for residential work, and the push-button advance keeps things predictable. Convenience is the headline—less tinkering, more trimming.

Recommendation

I recommend the EFD-080 spool for owners of Black & Decker’s LST560C and compatible EasyFeed trimmers who value reliability and ease of use. It delivers consistent push-button feeding without the hassles of bump-feed heads, and the factory wind quality translates to fewer interruptions. Just make sure your trimmer specifically calls for EFD-080; compatibility is not universal across the brand’s lineup. If you need heavier-duty cutting or your model requires a different bobbin geometry, look to the correct part or consider rewinding with a compatible heavier line. For the intended tools and typical yard maintenance, this spool is a simple, effective upgrade that keeps the work moving.
