Thanks for the reply, unfortunately I can't show you a unbroken balancer as removing one is like tripping a mousetrap. I have added some pics showing the clip that attaches to the bottom of the sash it attaches to the balancer via the string that broke. There is one balancer on each side of the window. Hope the pics help .

Thanks for your efforts the sash is wood but the liners are plastic. My house was built in 1990 so we are not talking an old house here. Looks like I will have to live with using a block of wood to keep the window open or just replace the windows in the house $$$.
Okay thanks for your help
