Window channel balance replacement

These stamp codes only tell us spring strength of the balance. To know what kind you need, we have to see the balances out of the window, and specifically the nylon fittings on either end. Now, Rollyson windows oftne use our Series 371 balances, so this may indeed be what you need; but there's some other possibilities as well, so it's best to see to confirm.

See our S380-28 or S385-28, depending on the depth of the bottom nylon shoe. You'll need a stamp option of 2740.
