I have a channel balance that seems to be Series 385 but it is stamped with 1010X for a bathroom window and I do not see an 11" option anywhere. Can I get one like this?

Yes! We can help. But since it's a special length, it will have to be custom made. Check out this Custom Channel Balance Request Form I've started for you based on your specifications and fill out the blank fields. One of our representatives will get back to you with a price quote and an item to add to your cart.
