----------------------------Original message---------------------------- Greetings, Another State agency is disposing of a surplus map case - your typical standard 5-drawer Mayline Co. map case. We are "picking it up from the trash" and hope to stack it on top of one of existing map cases. Anybody want to explain to me how to remove the "tops" of the Mayline cases so that I can add this donated one? I don't have any manual and can't figure out how the "tops" and the individual 5-drawer units are attached and locked to each other.
