We recently supplied a trolley solution to a window fabricator which allowed them to store their double glaze units and sashes like a toaster – all stacked side by side, separated so they didn't touch each other, and with each individual item easily accessible. Compared to stacking them against each other like a sandwich, these toaster racks provided immediate benefits – less rework through less rub damage, quicker access to individual units, and better health and safety as staff members were not sorting through units (or leaning them against themselves) to get to the required unit.

Storing like a toaster doesn't work so well for large volumes of larger units as access is from the edge, which becomes more difficult for heavy units. But for 80% of a fabricators glass, the "toaster" style works really well.
