Unitron 8x10 Locking Paper Safe w/ 4 shelves

Description

This 4 shelf paper safe is actually 2 stacked Unitrons that interlock into one unit (see photo). You can lock 2 of the doors at a time with the red clamp.
Back in the day when I was printing glossy and luster in b/w and then also color, this was a very useful darkroom accessory as you could lock the color side when printing black and white and avoid wasting paper.
