This ADF Molle Shelf for the 2018-2023 Subaru Crosstrek requires both the driver and passenger ADF Molle Storage Racks, since the shelf bolts between them and cannot mount on its own. Once the racks are in, the shelf spans the cargo area about 17 inches off the floor and measures roughly 13.9 by 43.75 inches, splitting the space into an upper deck and a lower bay. It is cut from 11 gauge 5052 aluminum with a textured black powder coat and stainless hardware, and ADF rates it for up to 100 lb. Flat items like a recovery board, folding table or camp stove ride on top while bins slide underneath. On a Crosstrek loaded for a weekend in the Kootenays, that second level keeps heavy gear from stacking on anything fragile. Shipped across Canada by Flat 4 Offroad in Calgary.
