Searching for s29 1027 11

A quick learner says:
From inside the house, looking at the window, the one reading S29102711 is on the left hand side. L10/14278-88 is on the right hand side. I need one of each.

Thank you for reaching out to us. For the 1027 stamped balance, see the 24-1033. As for the balance stamped L10/1427, check out the 24-L10-1427. The 24-R14-1027 is the right-handed balance. 

Please note that we always recommend replacing your balances in pairs. Pairing a new balance with an old one would cause the new balance to wear out much faster since it has to pick up the slack for the old one. Just something to keep in mind!
