Genuine Kirby Vacuum Cleaner Belt, for older models, for 505 THRU TRADITION models. Original Kirby part # 159056.

To preserve optimal performance of your Kirby home care system, Kirby manufactures genuine belts for replacement. Although buying an imitation belt may seem more affordable, they can stretch and break, in turn damaging not only your Kirby system, but your carpeting also. Genuine Kirby belts are sized properly for your device and custom engineered for peak performance with the belt lifter.
