Drop-in box for Savute Drawer Systems - By Big Country 4x4No rotomolded plastic here. This is a custom made metal box specifically designed to optimize your drawer kit. Think muddy, rust shackles, snatch blocks, chains and slings. It also does well fully loaded with canned food, dumbbells, sledgehammers and rocks. It is overkill for packing clothes or soft goods but it does that job just fine, too. Size: Typically 16" 18" square and matched to your drawer height. Yes these are custom to your drawer width so
