The SINGLE LID SERIES from UWS is a low profile box with a single piece lid that opens vertically to 90 degrees, not partially open like others. Result? Lots of accessible space that lets you load golf clubs or bulky tools easily. Two super-duty gas cylinders lift and hold the lid open. This lid, available only on a UWS Box, is a solid structurally foamed lid* that will stay true to shape and virtually eliminate adjusting of latches. UWS boxes are like vaults. . . secure and sealed against the elements. A Classic look yet built tough!
