2800 Window balancer
Greetings. For your balance, it looks pretty close to both our Series 380 and Series 385. The only difference between these two balances is the depth measurement of the bottom balance shoe. The depth measurement of the bottom shoe for the Series 380 is 1" and for the Series 385 is 1-3/32". Measure the depth of your bottom shoe, like in the diagram below, to determine which of these would make a good match. You will need to measure the metal length portion only to determine the length you need. Since your stamping does not match with any of our stamp options, you will need to weigh your sash on a scale and refer to the sash weight chart listed on the product page. Lastly for the take out clip, you can go with the 16-002. Get back to us and let us know if any other questions come up.
