What precautions or tactics did the coffins employ to conceal fugitive slaves?

Coffins designed to conceal fugitive slaves often featured hidden compartments or false bottoms where individuals could be hidden. They might also use deceptive labeling, such as indicating the coffin contained a deceased person, to evade suspicion from authorities. Additionally, some coffins were built to resemble standard burial coffins, allowing them to blend in with typical funeral practices and avoid attracting attention during transport.
