Will this tip over if I load one side heavier than the other?

The folding frame is designed for stable storage on a flat surface when all three levels are expanded. Keep weight distributed across drawers and store on a sturdy bench to prevent tipping—don't use it as a mobile cart.

Can I stack other tools or parts on top of this when it's closed?

When folded, the box lies flat, but stacking heavy items on top can stress the hinges and lock mechanism. Use it as a standalone storage piece rather than a platform for stacking.

Do the drawers lock in place when the box is folded up?

The drawer mechanism is designed to stay secure during normal expansion and collapse. Test the action a few times before trusting it with loose hardware during transport—jerky movement can cause contents to shift.
