Abstract
A window balance assembly for installation in a window assembly can include a balance portion that is connected to a carrier that may have a first and second side. The balance portion may be arranged to be drawn out of the carrier on the first or second sides of the carrier. The balance portion may be a spring member or element. As the spring element is drawn out of the carrier, contact made between the spring element and the carrier may generate a friction that results in undesired chatter of the spring element and/or audible noise from the carrier. This friction may be reduced by controlling the contact made between the spring element and the carrier. Further, a reduction of friction between the spring element and the carrier may result in a reduction in spring chatter and a reduction in audible noise from the carrier.
