Same Fit as all models, just a added 7' of depth for more storage space. Same dimensions all around except the depth. The sinlge lid Series from UWS is a lower profile box with lips opening to a full 90 degrees; thus easily allowing it to be loaded with large and bulky items. Two super-duty lift cylinders help raise and hold the Structual Foamed Lid open. Single lid boxes ar the most popular selling box because of their large capacity and easy to use features. UWS boxes are built like vaults....secure against the elements.
