Overview

Ships as a 2-piece set, this chain is a direct replacement for Black+Decker LCS1240 LCS1240B Chainsaw models. Running a dull chain forces the motor to work harder and shortens the life of your bar, making periodic replacement essential.

Key specifications

  • Bar length: 12”
  • Quantity: 2 chains per pack

Compatibility

Manufactured to fit Black+Decker LCS1240 LCS1240B Chainsaw without modification. Cross-reference your saw’s model number with the product listing to confirm compatibility.

Installation notes

Disconnect the spark plug wire or remove the battery before changing a chainsaw chain. Remove the bar cover, release bar tension, and take off the old chain. Place the new chain into the bar groove with the cutting teeth facing forward on top. Reinstall the cover, adjust chain tension until snug, and test by pulling the chain around the bar by hand. Re-check tension after a few minutes of use.

Common questions

Q: Will this 12 inch chain fit my Black+Decker LCS1240B, or is it only for the LCS1240?

Yes, this chain is made to fit both the Black+Decker LCS1240 and LCS1240B, since both use a 12-inch bar setup. As long as your saw is still using the original 12-inch bar size, this replacement chain should be the correct fit.

Q: Does this 2-pack chain come sharpened and ready to install on my Black+Decker LCS1240 chainsaw?

Yes, replacement chains like this are typically ready to install and use right out of the package. After installing, make sure the chain is facing the correct cutting direction and adjust the tension so it sits snugly on the 12-inch bar without sagging underneath.

Q: How often should I tighten or maintain this chain on my 12 inch Black+Decker LCS1240?

Check chain tension before each use, especially when the chain is new, because it can stretch slightly during the first few cuts. It also helps to keep the chain clean, ensure bar oil is flowing properly, and touch up the cutters with a file or replace the chain once cutting performance drops noticeably.

Compatibility

This part is verified to fit the following equipment. Always confirm the model number stamped on your machine before ordering.

Not sure which chain you need? See our guide: How to count drive links or Chain pitch, gauge & drive links explained.

Before you buy — how to verify fitment

  1. Find the bar stamp. Look on the side of your current guide bar for the pitch, gauge, and drive-link count.
  2. Match all three numbers. Pitch (3/8 LP), gauge (.043"), and drive links (45DL) must all match.
  3. Check bar length. Measure cutting length from the tip to where the bar enters the saw body — this should match 12".
  4. Confirm your saw model against the compatibility list above. If your model isn't listed, the chain may still fit if pitch/gauge/DL match.

Frequently asked questions

How do I know this chain fits my saw?

Match three numbers: pitch, gauge, and drive-link count. All three must match the stamp on your current bar. If even one is off, the chain won't fit safely.

How do I measure pitch and gauge?

Pitch is the distance between any three consecutive rivets, divided by two. Gauge is the thickness of the drive links — measure with a caliper or check the bar stamp. Our guide covers both in detail.

How long does a replacement chain last?

With proper tension and occasional sharpening, an aftermarket chain lasts 3–5 cords of firewood or about 5 hours of active cutting — roughly the same as OEM.

Can I sharpen this chain or is it single-use?

Absolutely sharpen it. A quality replacement chain can be sharpened 3–5 times before the cutters are too short. Keep a round file matched to the cutter diameter.
