SnapOn box part number question ?

[davox]

Does anyone know what the difference is between the following SnapOn bxes:
KRA5315PC and KRA5315DPC.

The KRA5315DPC is the current part number on the SO web site. I have been offered a KRA5315PC that is 4 or 5 years old. They are both black KRA boxes but what is the significance in the D in the part number.

Thanks in advance.

a couple of years newer and maybe newer casters. yeah the casters are a softer caster that makes the box very quiet when rolling around the shop. the other casters were loud and noisy( the box rattled real bad) when you hit little bumps. the new casters cushion the bumps. helps with rolling over hoses and cords.
everything else is the same as far as I can tell.
