Overview: The Thule 668ES-Frontier ES Cargo Carrier mounts to most factory installed and aftermarket vehicle roof racks.
Fit: The Cargo Carrier requires an aftermarket or factory installed roof-mount rack to mount to the roof of your vehicle. This box may cause interference with some station wagons and hatch backs. Please check the Thule Fit Guide to determine compatibility with your vehicle.
11 Cubic Feet and 110 lb Loading Capacity: The Cargo Carrier offers 11 cubic feet of space and handles and loading capacity up to 110 lbs. Make sure that loads are evenly distributed inside the roof box. Do not exceed the maximum permitted load of 110 lbs for the box or the maximum permitted load for the roof as recommended by your vehicle manufacturer, as well of the maximum load of the roof-rack.
Construction: The Cargo Carrier is made of vacuum molded ABS high grade impact and scratch resistant material.
EasySnap Hardware: EasySnap hardware mounts directly to most aftermarket and factory-installed roof racks in seconds.
Passenger Side Opening System: The cargo carrier will open from the passenger side for safe curbside access.
NO-GO Central Locking, One Key System: The carrier is easy to open and close thanks to Thule's NO-GO Central Locking, One Key System. Insert the key and turn clockwise to the unlocked position. The key can only be removed when the box lid is closed and locked. To close, press down on the lid at the front and rear of the box. Turn the key counter-clockwise to lock and then remove key.
Weight: The Thule 668ES-Frontier ES Cargo Carrier weighs 33 lbs.
