How long is the chain for part 0115388

Well you're no help

Well you're no help
It's difficult to help with such scant information.
Please bear in mind this site is run by volunteers, so expecting a response within TWO minutes is a little unreasonable.

Is this for a ceiling fan ?
If so which manufacture is it?

This is also not a manufacturer's site, as I think many people believe.
This is a DIY help site.

Well excuse us. Part number you note could be for a fan, a chain saw etc. We can't read minds on days ending in "y".
