I think these are 3/8 inch 34 inch white tipped series 900 spiral balances for my tilt window. The part the screw went through on the top is made of plastic and they started to break (with a very loud bang) shortly after we bought the house.
My question is this: My current balances are encased in a white plastic sleeve (which became brittle and broke off bit by bit. Do yours come in white, or have a plastic white sleeves I could use? We don't want the metal sleeves showing.
Thanks!
