The lockable box for the loadbay. Very handy storage when your single cab or double cab does not have a canopy. It fits before and after the wheel well. It is the same width and height as the wheel well. This greates a continuous 'wheel well'. It serves as handy secure packing space and is strong enough to allow you to sit on it or stand on it. The lid when opened rests against the side of the vehicle load bay and will not drop on your fingers all the time. When bought in sets it will be keyed alike. The single cab can take 4 and the double cab can take 2 boxes. After 2006 vehicles will take one less as the petrol filler on the right rear is in the way. It has a seal on the top door joint and will be pretty rain and dust proof.
