SWISCO - The Replacement Hardware Authority

Expected balance life

A quick learner from Palm Coast, FL says:
I have ordered several SWISCO balances over the last 10 years.
Is there is certain life that can be expected from them?
The replacements, while used very little (opening/closing of the windows), seem to have an awfully short life span.
Is there anything I can do to prolong their life?

Well, it would depend on the balance. Typically, you can expect a balance to last 5-10 years, depending on how often it's used. What balance exactly are you using? Do you also still have the original balances handy? It's possible the new replacements don't match the original exactly. Mismatched balances could wear out faster.
