3/8" LP · .050" · 40 DL chain: which saws it fits
A 3/8" Low Profile pitch, .050" gauge chain with 40 drive links. It is most often found on 10" bars, and fits 137 chainsaw and pole-saw models from 10 brands in Oregon's fitment data. Bar length alone doesn't decide fit — all three numbers have to match your saw.

Confirm it's your size
- Read the bar stamp. Near the tail of the guide bar you'll usually find pitch, gauge and drive links, e.g.
3/8 LP .050 40. Some bars stamp the Oregon bar number instead — look it up on oregonproducts.com. - Count the drive links on your old chain — the teeth that ride inside the bar groove, not the cutters. It must be exactly 40.
- Low profile is not full profile. 3/8" LP and 3/8" full-profile chains share the "3/8" but are not interchangeable.
- If the stamp is worn off, the owner's manual lists the bar and chain; find it on the manufacturer's support site.
Easy to mix up with
- 3/8" LP · .050" · 39 DL — same pitch and gauge, shorter loop (usually 10" bars)
- 3/8" LP · .050" · 44 DL — same pitch and gauge, longer loop (usually 12" bars)
- 3/8" LP · .043" · 40 DL — same pitch and length, thinner drive links; it won't sit right in a .050" groove

Source: Oregon part-finder fitment data, retrieved 2026-07-06. We list a model here when Oregon recommends a 3/8" LP · .050" · 40 DL chain for one of its bar lengths; we haven't fitted each saw ourselves. Some bar configurations in the source don't give a drive-link count and aren't included — if your saw isn't listed, count your chain.
