A 2840

Question

From what I can tell the stamp says "a 2840". Both sides of the window unit have the rope and hook pulled out from the track. I believe that I need to replace both sides but would like help with the replacement part as well how to remove and replace each side. Any help is greatly appreciated.

I think we can replace this balance, but it will have to be a special order. I think you might have something like our S770-29 but with the bottom clip swapped out for our 62-105 hook. It would also have the 29D stamp for sashes weighing 23 through 28 pounds.

Please review these details and let me know if they match up with what you're working with now. I would also like to know how many you need. Once I have that information, I'll email you a price quote and order link.

To remove the old balances, first tilt in and remove your sash from the pivot shoe. Then use needle nose pliers to unhook the 62-105 hook from the pivot shoe. That will allow you to raise the balance sitting on the nylon bushing and remove it from the track.

To install a new balance, first place the balance above the nylon bushing use your needle nose pliers pull down the hook to attach it to the pivot shoe.
