Discoverer Sub Zero Core Trays are available in all sizes and both Series 1, 2 & 3. Tested to -50degC / -58degF and designed to withstand prolonged freezing conditions. They are manufactured from UV Stabilised premium polymer and are immune to Corrosion, Deterioration & Infestation.
Typically we supply this Core Tray/Box in the Series 2 model, as it's mainly used in Cold Climate countries around the world, as this model is best for international sea shipping due to the nesting feature when trays are empty.
However if you'd like another model of the Discoverer Series in this specialised material please make the request. Minimum production run quantities will apply.
