These are two nominally 118 cm Thule aero/wing (quiet) roof racks with fixtures/mounts for attachment to a vehicle which already has rails down each side of the vehicle. The actual proven rail separation used by owner has been in the range of 99-115 cm apart (the fixtures/mounts slide in slots on the rack). The aero/wing design accommodates other fixtures/mounts from Thule or some third party suppliers. They have some wear marks from normal use, and are fully functional as new. There are two keys for the common locks (on the fixtures/mounts). This sale is cash on collection or e-transfer in advance only. The price is non-negotiable, with no warranty or returns possible.
