Paterson Plastic Developing Tray Set - 12x16"

Each tray's package weights 1.4 lb, so all 3 will be 4.2 lb.

I believe the depth is 3". I used 1/2 gallon of developer/fixer but found it is unnecessary. In most cases, if the bottom 3/4" of the tray has liquid, I can develop 8 x 10 wet plate (aluminum)and 8 x 10 glass plate with no issues. The plate is completely under the liquid and there is still enough room to agitate the liquid without it spilling over the edges.

Including the spout is 20"x15"
