SWISCO - The Replacement Hardware Authority

proper spiral balance

A home owner from Knoxville, Illinois says:
I have a Tempco Vinyl replacement window about 25 years old that need balances. The window has triple glazing and has a 5/8" piston and a white tip. But the sash weight is 14.6 pounds each. Your 600 series balances look as though they would fit but which tip should I go for, the white like I have or the red according to the weight?

Thanks for posting. Are you referring to the weight rating chart we display? If so, I recommend sticking with that. Some older balances used White Tips, but they used a different kind of rating system. Newer White Tips aren't necessarily the same as older White Tips. When in doubt, always go by the weight of the sash.
