Fiber innerduct sock brand name

[This is hardly a sure hit as the best forum, but it is communications.. if no answers, I'll try another place..]

I'm seeking a {brand} name for the protective sock that goes inside a polyethylene fiber duct. It's a woven hollow tube; you pull in say 3 of them, then the fiber is pulled down the middle of each sock. This not only protects fiber from abrasion but also tangles with adjacent fiber bundles.

I can picture it, but my Googlefu is weak, and I can't a noun, brand name or supplier.

If I'm correct, then even I'll be amazed.

I search for "accessories" for fibre optic.

I've used the Maxcell product before with success.
