This is a replacement cable for Vibo lifts. It is for the 3000lb capacity lifts (capacity stickers on EVERY Vibo brand lift). The beam should measure 108″. To find the beam, measure the inside distance between the uprights that you drive through. There are two side cables on every vertical lift. This cable measures 17′ 6″. One is on the winch side that runs from the shallow end to the deep end. The other is on the opposite side that runs from the shallow end to the deep end. A set of 5 replacement cables is available separately. Price is for ONE cable.
