Balancers

Based on your stamp, I'd say you have a 2520 stamp option on a 26" balance. It'll either be our S385-26 or S380-26, based on the bottom shoe. Measure it as shown at the bottom of this post, and if it measures 1-3/32", go ahead and get S385-26. If it's only 1", you need S380-26. You can verify the length by measuring from one end of the metal to the other, and you can verify the option by weighing the sliding window sash, which should weigh between 9 and 15 pounds.

If you need the "take out clip" shown on the top right, take a look at our 16-002.
