Looking for 29" long 2840 Balance channel

The pivot shoe you show looks like our 15-105. The balance, on the other hand, will have to be specially made. I believe it would be our S770-29 channel balance but with the clip at the end of the cord swapped out for our 62-105 hook. Does that look good to you? I also would go with a 29D stamp to replace the old 2840 for sashes weighing 23 through 28 pounds. You may want to weigh your sash just to confirm this is right.

If that all looks good to you, please let me know how many you need. I can then email you a special order link and price quote.
