? Ceiling Vent Tool

here you go
Barker vent stick and Knob
extra knobs available in (2) pack

did not know what the OP was talking about, until i looked it up
climb a ladder to open vent ?

if he had said use a step stool
i would have caught on quicker

i'm only 5'6" and i can reach mine ok

I remember seeing something about one. A guy took and notched a piece of PVC pipe to match the knob of the vent then added a smaller diameter section of pipe as a handle.

Not sure what you have but maybe a piece of PVC pipe with a notched end?

Here is what I use

So far no joy searching for this. Perhaps some further detail would help.

Not sure which vents we're talking about.. I know I don't need a ladder to open my fantastic bedroom fan!
