Thanks for posting. See either our S380-34 or S385-34 Channel Balances. The only difference between these two balances is the 'depth' of the bottom nylon shoe. Now the shoes in your old balances look a bit banged up; if you have trouble discerning the depth, you may need to pull a balance out of an identical window in the house for comparison. Finally, you'll nee a stamp option of 3340. |
