Regarding weight capacity, it’s the same as most other roof cargo carriers of this size at around 165 lbs, of course, due to the limit of the vehicle roof itself.

Inside the FARAD you can store equipment up to 75.5 inches long and 36 inches wide, don’t let the practicality fool you this box is stylish and aerodynamic.

Then you wouldn’t have to worry about any major wind noise or a massive drop in your MPG due to wind resistance. But we still recommend not leaving your roof box mounted all the time, as it may be a target for theft.

The FARAD opens on both sides, giving you easy access to all of your goods and equipment. Some consumers have reported difficulty closing and locking the three-point locking mechanism.

Due to safety concerns on the road we recommend strapping the roof box just in case to eliminate any chances of its opening.

As we mentioned earlier the FARAD is one long and wide roof box, so it’s likely to overhang from the front or rear, in case you have a rear hatch we advise you to not use it during the trip or just try to place the box slightly to the front of your vehicle.
