Assembling Harvard Stacking Posts

And for those who have elected to purchase Harvard or Cherry Ridge style trays in multiple configurations, you may be required to assemble the trays and the stacking posts when you receive your trays. They are normally shipped from the factory unassembled to avoid damage in transit. Never the less, they are actually very simple to assemble. But, if care is not used, damage can occur to the trays.

Using Stacking Supports with Hedberg Trays

Stacking supports (07256) are designed to be used with Hedberg, Classic, American Legal and Archetype series desk trays. These supports can be added to existing trays at any time to create a vertical stack of trays, as long as all the trays are the same size, (ie: all letter size or all legal size, not a mixture of letter and legal). There is a youTube video that shows the correct installation of these supports located at "Letter Tray Stacking Supports"
These supports will not work with the Harvard or the Cherry Ridge series of trays due to the difference in wall thicknesses the supports are designed for.
