Sizing: Carolina Custom Foam suggests replacing the foam to work with the item you wish to store. Because there are so many different thicknesses of foam, we carry a few that will help you get very close to spec.
Corners: We highly suggest you push the corners of the foam, into the rounded corners of the case. This will give a tight hold and the foam will conform to the corners overtime, giving you a tight, perfect look.
According to the case manufactures website the spec are:
Lid Depth: 1.18 in. Base Depth: 4.93 in.
