The length of the channel is 24, the stamp on the channel says 2590 and I don't see that number listed. I'm thinking that the series 380 is the right one but the stamped number is throwing me off. Please see attached photos. I will need 2 sets.
Thank you in advance for your help.

Hi, David.
Depending on the depth of your bottom shoe, you could have either our Series 380 or Series 385. These two balances look very similar but the important difference is the bottom shoe depth. The Series 380 has a 1" deep shoe and the Series 385 has a 1-3/32" deep shoe. Measure as shown in the image below to see which one matches up best.
A balance with a 2590 stamp would usually measure 26" long for the metal channel but I'm wondering if whoever made yours used the wrong stamp. You may want to double check this measurement just to be safe. If it's still measuring as 24", you will need to weigh your sash on a scale and refer to the chart under the product description on the S380-24 and S385-24 product pages to determine the correct stamp option.
Let me know if you have any questions!
