Mystery top lid for toolbox?

[crankshaftdan II]

13"x8 5/8"/1 1/2" deep looks to be well made and HEAVY! Nice red PJ and the ends have flanges for like fitting down into the box top? Looks like it was not used and orphaned from the box. Anyone seen one like this or know who the mfgr might have been? Thanks......Cranky

Cranky, looks an awful lot like the tray that came in Milwaukee branded power tool cases. They're real nice boxes, have a couple of them here.

Not for sure,but maybe the snap on crowd could verify.....

Guy at work had one for his snap on on box. It fit in the lower drawer of his box. The 2 folded lips allowed it to hang on the sides of the drawer. He stored long stuff under it since it didn't rest on the bottom, and he used it as a quick "grab and go" tray.
