This is an adjustable rack, will fit most pickups or flatbeds. It has the optional insert, which can be easily removed. I retired and don't need it any more, so you get a bargain. It protects your rear window, provides a place to lean long items without touching the cab or high brake light, provides tie-down points, and I will throw in a steel flat plate to mount a magnetic light bar, never used.
