Folding Cornell system unit pinning trays are a BioQuip innovation intended for those with low budgets, or for those whose supply and storage areas are limited. They have the same dimensions as standard Cornell series trays, and can be assembled as needed and in the quantities desired.
Trays are made of heavy white coated chipboard (100% recycled material), cut and prescored. They fold neatly and easily into sturdy double-walled trays, and are secured in position by gluing and installing 5/16″ #1028N polyethylene foam pinning bottoms. The adhesive is especially formulated for positive adherence of the foam to the tray bottom.
Trays are sold in kits of one dozen, and in lots of 100 and 1,000. All 4 sizes of Cornell trays are 4-3/8″ wide and 1-5/8″ high (112 & 42mm).
