Sash weights are composed of heavy lead or iron cylindricals that are contained inside a concealed cavity, and connected by ropes to the movable window sash. They provide counterbalance, allowing the window to be closed and opened without the need for mechanical or electrical devices. The sash weights are usually neglected or ignored by homeowners, and are turned into scrap when they fail; therefore you may have to search for replacements.

They can be separated by using a knife and a mallet.
