I've seen the plumber snakes.. and electrician snakes. All look to be atlest a 3/4's to a full milimeter thick.
I'd say Wiper insert, and use the snakes for handels its what i do, works great, they snap off so you don't have to shop them, same witht he wiper blades. Just buy a few one one at a time untill you find thick ones (width wise)
I seen that to in my catologe, i would think maybe, but then again probobly not. But i have never seen them.
Shrubs a good buy to ask for this, he picks many a lever down dere in Derby
