Hello my Vinal window channel balance is not working at all. it is 21 years old and the springs are rusty. I cleaned and added lithium lube and still not working. so I think its time to replace them.
On the metal part the stamp is 08 007 1420. The overall length is 16" and the metal frame is 15". The frame with is 1/2" wide.
Can you help me select the correct product?
Thank you
