We can replace this balance, but it will have to be a special order. Basically we'll use our S770-28 channel balance with a 28D stamp and with a rivet installed in the top hole. The S-hook is sold separately and would be either our 19-029 (short) or 19-030 (long). The 28D stamp indicates how much weight two balances working together can support. Specifically, 28D means these balances can carry 23 through 28 pounds. You may want to weigh your sash on a scale to confirm that it falls in that range. In the meantime, I'll email you a special order link and price quote for 2 of these right now. Let me know if you wanted to change any of these details. |
