Channel balancers for storm door

Question

This door has an upper and lower sash. Both are operable.
Balancers for upper are marked 37B BSI VO. Lower are marked 20B BSI VN. See photos. Photos of each end are also included. The channel cross section measures 7/16" x 3/8"

What's the best fit for replacement?

Hello, thank you for posting,

Your balance resembles the Series 800 channel balances. Unfortunately this Series has been discontinued and we only have a limited amount of stock left. For the 20B stamp option, review the S800-21 that has a 21" long metal channel excluding the nylon attachments.

Unfortunately we are not able to provide a replacement for the 37B channel balance as it is no longer available. Please review and we apologize for the inconvenience.
