These 120cm-wide heavy duty roof bars support a maximum load weight of 90kgs and they are made from durable aluminium. They are designed to fit vehicles with factory-fitted roof rails and they're easy to fit thanks to its adjustable lockable fittings. Please note, these roof bars will only fit raised roof bars that have a space underneath the rail. They are not suitable for solid raised roof rails as the fittings need to fit around the rails. Also, when adding load to the roof bars, please check with the vehicle's manufacturer handbook to find out what maximum weight it can take. This includes all Roof Bars and Security Locks.
