It's possible to fit Dropracks to most vehicles with fixing points, and we do list a Dropracks option for some vans (the most popular being the VW Transporter). If you select your vehicle here you can see if we list a Dropracks option for your roof.
The bars on the Dropracks fit where the fixing points are. If we don't list a Dropracks for your vehicle, we would need to know how far apart the fixing points are (measured longitudinally to the nearest mm) in order to supply connecting bars that are set to the correct distance for your car, and recommend the correct parts to connect the Dropracks to your roof.
There are some restrictions, i.e. if you have a van that is particularly wide it may be too wide to fit a Dropracks using the original fixing points on the roof. This can be overcome if you can use the Thule SpartClamp system. The Thule SmartClamp System is suitable for H2 Ducato, Jumper, Boxer vans from 2007 onwards and Movano from 2022 onwards.
