Trouble threading Doorbell Wire through an existing hole

[Midwest]

Cotton thread and a vacuum cleaner
Hold the nozzle over one hole, and dangle a length of thread in front of the other hole.

You’re another one, that’s over stepping the mark. Young kids visit this forum you know!

I would recommend my pet caterpillar Cecil but again, I think he’s a bit too porky to get through that hole.

If its getting stuck when you push it in and through. Then maybe apply a small but of lubricant spray. It should ease it through a bit easier

Coat hanger wire with a small hook formed on the end in the hole from one side. Length of thin wire (1.0mm cpc, or thinner) doubled over and pushed in from the other side. Fish around with the coat hanger until you get a bite.
