The depth of your bottom "shoe" looks to be about 1-3/32", and the length of the metal channel is probably 27". If that's the case, use our S385-27 side-load balance. This series is very popular in California. The spring weight option for 26 4 is typically our 2640 for window sashes between 19 and 26 pounds. Verify that your sash falls within that range.
