flying wire covers?? what r they called

[Smithacb]

OK, really silly question. What are the covers called that cover the flying wires attachment points on the wing surface?
Who sells them or are the fabricated by the builder out of anything they can think of/have?

A Pitts s-2B has some lovely ones, look professional, I've scoured Spruce & Steen, but just can't think what they might be called or seen any for sale.

Thanks Guys.
