Pull-chain Finials for Ceiling Fan

If, like me, you have trouble remembering which pullchain turns on the ceiling fan and which turns on the light, attach these finials -- the dangly bits at the end of the chain... I had to look up the correct term -- and yank unerringly.

I happened to have two differently sized pullchains, so there is a lock part for each size.
