Model 662-0-02 Underbed Box, Aluminum, Jumbo, 20.0 cu ft is rated 3.5 out of 5 by 2.
Rated 2 out of 5 by from Not the best box Bought this product based on the Weather guard brand recognition. I expected a lot more based on the reputation of this brand. The box is definitely a lower grade than other Weather guard boxes I have had so that's probably why this box is almost $200.00 less. It was very challenging to install on a 2016 F-150 with bed liner. It required me to elongate the slot to get the hold down hardware installed and I was only able to get one on each side. Secondly, the box is unable to be installed all the way to the front bed edge of the inside frame as it prevent the lid from opening and will hit the rear glass. I had to leave a 1" gap between the inside bed frame to make it work. Lastly, the push button locks are not operating correctly or at all and are defective. Other boxes I have had, the push button is able to be turned to locked and then pushed in. Not liking this box at all and will returning it back.

Rated 5 out of 5 by from 4 jumbo boxes mounted on F550 flat bed I went to truck show and looked at all Mfg's boxes. I liked Weatherguard very much. Mounted two 24" deep by 60" long and two 24" deep by 48" long boxes on flatbed (bed is 12 feet long) INSTALLED 3/2016The good:Boxes hold a good amount versus a utility box setup.Heavy duty overall.Doors seal well. No leaks and easy to close with one lever. Adjustable chain on.door is a must over others fixed cable setups!!!The bad:These boxes are so deep you have to extend chain to drop door to reach into box. I use a single cable only on one side. Cable is just chain and adjustable.The boxes are not designed for above bed (flatbed) mounting so have to be set hanging over flatbed.On one box the rod used to open and close fell off and took some doing to open.One lock is hard to lock unlock.First set of boxes for 60" wide both came in dented and front doors poorly made, and chips.. The factory replaced but took weeks. NOT SURE WHY MFG. DOES NOT MAKE FLATBED TYPE BOXES???I plan to add boxes above these for more storage.

How do you drop lid to 180 position?

With chains disconnected lid will drop to 150/160 degrees. Bottom of lid comes in contact with bottom of drip rail and stops. Loosened hinge screws to try and adjust no success.
Asked by: Dennis
I apologize for the information that is displayed on the underbed boxes. We are in the process of updating the information. This lid will unfortunately not drop to a 180 degree angle. It will be around 150-160 degrees like you stated.
