Can you match this ident. with replacement hardware?



To help us identify the correct replacement hardware for your application, please remove the balances from your window and take a few pictures of the attachments on both ends of your balance. This will help us find the appropriate Series. In the meantime, you can browse through our Tilt Window Channel Balance category and see if you can find the Series you need.






I also provided the weight for each window.
28E WAS 31.O lbs.
28F " 44.0 lbs.
22E " 24.5 lbs.
Your load rating for 28F IS 32.0 lbs. to 36.0 lbs.
Do you make a 28G with a higher load rating?



Thanks for getting back to us. I think you may be confused. The stamps aren't serial numbers, they are indicators of the balances' weight ranges. 28G can't have a higher load rating because it is the load rating!
That said, we can make Series 770 balances to accommodate these window sash weights, but a few of them will have to be custom made.
Let's start from the top:
1. I recommend the S770-28 with a 28E stamp option. 28E can support a window sash weight range of 28 through 32 pounds.
2. This balance will have to be custom made with a stamp of 28I, which can support 43 through 45 pounds.
3. Since this Series 770 is 28" long and for a window sash of 44 pounds, I'd once again recommend the custom balance with the 28I stamp.
4. This balance will have to be custom made as well, this time with the 22E stamp. The 22E stamp can hold 24 through 27 pounds.
I hope this information has helped you! I'm going to email you a purchase link and price quote for your review. You can use this to place an order on our website. Please let me know if you have any other questions.
Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
