What is this chain?

[kevin j]

Found in a box I bought years ago and never opened until yesterday.
3/8, full comp, chisel chain.

I don’t have a rim here but it seems that it might clear a rim but not a spur on the back side as the tooth comes away.
Or is this the strangest QC failure at mfr?

That sure is strange looking. Send it to Oregon with a nasty gram. "HEY! I'd like a chain where EVERY driver is cut!"

It was 'a thing' for a while. I never understood it. Didn't even last as long as 'New Coke'. Run it.

The hook in the chain is to scoop oil in the upper bar and lube the links of the chain. This design would scoop 50% less oil.

Looks like the safety humps on wrong.

They designed it like that and it is just fine. It didn't last long and I rarely see them come in for sharpening anymore. 72LG style
Stable link is what they called it

That is Oregon's inverted hump chain .

They'ed make sure that the sprocket won't wear out.

So what was the marketing pitch for ‘stabil link’? What was it supposed to do better then past designs? But apparently didn’t ...

Found some old posts, going back 11 years:

Don't really answer the question.

It supposedly reduced vibration, keep the chain tracking better. It mostly packed crud into the bar rails and sprocket tip. It did not feel as though it reduced vibrations, although the vibrations it would reduce would largely be covered up by other vibrations.

Use it up.
