Slide Locking Hang Parts Trays

These parts sorting trays are designed for small projects that only need a single or for larger projects that may take multiple trays.  Sometimes projects can’t be completed in a single setting, or other projects may have to take priority, so a lid can be added to help keep parts from being spilled or trays can be stored by installing them in the under-desk/shelf bracket.  

Trays slide together and lock in place to make stacks of trays.  The under-desk/shelf bracket can store 1 tray or a stack of trays in each slot.
 
There are different tray designs to choose from and all trays slide and lock on to one another. There are 3 under-desk/shelf brackets to choose from for 1 slot, 2 slots, and 3 slots.  Brackets are designed to be placed next to one another and hold their position so to keep them from getting to close when installing.
