Has anyone tried to “tune” the ladder? That would be awesome if your ladder would wolf whistle.

Works great!
Got a little sticky with the foam. Acetone cleans it right up

I have thought about using the foam for years but have never done it. Instead I have just put duct tape over the holes and replaced it about every 2 years. I think I’ll give this a try.

I bought a fibreglass ladder a number of yeats ago (Werner i think) and it had plastic plugs in the rungs
