A broken window rope means that the sash has lost one of its two counter weights, and will no longer stay up. We replace broken ropes with copper plated steel chain. And occasionally we have to repair a malformed counter weight that had been catching a wall inside the counter weight channel.

  • The ropes broke and the sash would not stay open.
  • The sash counter weight would get caught in the channel and had to be reshaped.
  • The rope is replaced with chain, and the counter weight is put back into its channel.
  • The sash works fine now.
