There are 5 cables on every Vibo vertical lift. Depending on use, it is recommended to replace them every 5-7 years. This set of 5 fits the Vibo V40108 lift only. A capacity sticker is on EVERY Vibo lift. The beam should measure 108″. To find the beam, you measure the distance between the uprights you drive onto the lift through. Instructions on how to string the cables can be found on our website under “How-to ” tab. Then Vertical lift assembly instructions, page 7.
