Tololbox safety

I used to have a lovely old Snap-on KRL toolbox until this afternoon . Got some tools out of the top box and didn't shut the drawers properly . Heard a massive crashing sound and turned around to see the top box on the floor . It had hit a lower drawer on it's way south and ripped it right out . 

No idea why it decided to do it after all these years . It was only recently that a Snap-on dealer offered 2k cash for it . Kinda got it sorted and tools back in , but it took two of us to lift the emptied top box back on . They are quite a hefty lump unlike these peasanty oriental modern ones .

Rearranged box and sockets and spanners and other heavy drawers are now in the bottom box . 

Be careful out there  .
