Adjustable hold down for short bed pickup truck beds
Standard sheet goods fit in a short-bed pickup truck if you lower the tailgate. This method works fine until you encounter an incline. Then the sheets tend to unload themselves, leaving you with damaged goods, not to mention a red face.
To secure the sheets and prevent spillage, make this adjustable hold-down and backstop out of scrap plywood. The L-shape backstop rests under the sheet goods and has holes in the vertical support to accept a lynch pin for lock-in-place adjustability. The circular hole in the hold-down plate accepts a tie-down strap secured to the truck's bed.
