With small vehicles, once you're loaded with passengers there's not much room left for gear, which makes a roof mounted cargo box the perfect addition. The Force L is ideal for small vehicles, because even though it's sized to fit on smaller roofs, it has a large gear carrying capacity. The Force L can carry up to 16 cu. ft. of cargo (make sure you don't exceed the weight limit of your roof rack), 3-4 snowboards with a maximum length of 173cm, or gear for up to 3 passengers. The Force L is perfect for carrying duffle bags, carry-on type luggage, everyday items like groceries, gardening equipment or other household items. The Force L features a durable matte black Diamond-Textured AeroSkin surface, and the shape is aerodynamically designed, to cheat the wind and reduce drag and noise. This will improve fuel economy and make driving quieter and more pleasurable.

The Force L includes the Quick-Grip mounting system, which enables you to secure the box to the load bars in about 5 minutes. Loading and unloading the Force L can be done from both sides of the vehicle, thanks to the Force's dual-side opening feature. The 2 included straps can be used to tie your gear down in the box and prevent it from sliding around. Once all your gear is loaded, the 2 included One-Key lock cylinders can be used to lock the lid and lock the box to the carrier. The SecureLock feature ensures that all gear is locked and the box is properly closed prior to driving, because the key can only be removed when the box lid is closed and locked.

The Force L comes with everything required for installation, including detailed instructions. The limited lifetime warranty applies to the original purchaser of the product, and warrants the product against manufacturer's defects in materials or workmanship.

Review of Thule 624 - Force M Cargo Box
This cargo box is head and shoulders above the rest in quality. Real easy to install. On our first trip through West Virginia, we went through a terrific rainstorm. Rain was pelting us from every direction. The box didn't leak one bit.

Thule 626 Force XXL Cargo Box
First I would like to say that dealing with CARiD is fantastic. Easy ordering and free shipping on my product. Can't beat that! They also tell you to double check the product when it arrives to make sure it is good condition. The shipping company that delivered it took it off the truck and we looked the box over. He told me that it looks like the box is pulled apart a little so I took my time and took the product out of the box. It was in great shape, no worries. The diamond textured skin looks awesome can't wait to take it on a long trip. It fits my Westfalia great no problems at all. It also holds a ton of our camping "stuff" that we used to cram into the small van so now we are in heaven while driving as well.

Thule Carrier
I had purchase Thule 625 XL for a family trip I must say that I was very impressed with it size and capacity . It held 5 medium bags and a medium wheel suit case. It did require a two man lift but once it on top of vehicle and secured and was good to go. No wind drag at all it was like it was not never up there i am very satisfied with my purchase. Thanks DS.

Great Box - Quieter Then Previous Model
Looks great. Easy install and can be done by one person although 2 makes it easier. I bought this to replace the Thule Atlantis of the same size that was damaged. This is noticeably quieter due to the dimples design.

Easy Mounting...
The XXL is great for vacationing with my family. We have a Tahoe and with the XXL it's like having a Suburban. Actually you can probably put more in the XXL vs having just a Suburban. Went through a storm that actually caused power outages and everything stayed dry. My wife and I can easily put it on top and once on the OEM racks I can tighten the knobs and start loading it up.

Thule 628
Thule® 628 - Force L Cargo Box (74" L x 36" W x 16.5" H, 16 cu. ft.)
Love my new Thule 628. It looks beautiful and I don't even hear it on top of my car. Amazing aerodynamic design makes it super quiet . If you drive an SUV be careful because it might not fit in your garage make sure you measure first. Definitely recommend this product to someone looking!

Excellent Product
Easy one person install, which is amazing considering, it is big but it is light. Looks good with a carbon fiber finish, well made and just perfect for additional space for skis, boards and gear.

Great Box!
The box is overall great, but seems a bit flimsy. The plastic is a bit thin and I hope it will last. We only the box on one trip so far and it was ok. It has lots of storage and is easy to install.
