I bought 10 of these boxes without realizing that they don't stack. What was Plano thinking!?
While there is room for a gasket, it doesn't have one, but they are available from Plano for $2 each plus shipping (which is more than the gasket).
I'll probably return most of them and buy replacements from MTM that do stack.
Pros: Small aux compartment on top, solid build
Cons: Doesn't stack, no gasket
