Stackable insulated glass slat rack

A glass slat rack comprising:

• a base frame;
• a vertical slat rack attached to and extending substantially perpendicular from the base frame, wherein the vertical slat rack includes:
• a plurality of first slats extending substantially parallel to one another and running vertically, forming slots therebetween, each of said plurality of first slats having one end attached to a first slat bar that is (i) moveable towards the base frame to decrease tension on the plurality of first slats and (ii) moveable away from the base frame to increase tension on the plurality of first slats, and
• a first tensioner operable to adjust tension applied to the plurality of first slats by moving the first slat bar in a direction towards the base frame and in a direction away from the base frame;
• and
• a pivoting slat rack pivotally mounted to the base frame, said pivoting slat rack comprising;
• a plurality of second slats extending substantially parallel to one another and forming slots therebetween, wherein the slots of the pivoting slat rack align with the slots of the vertical slat rack, each of said plurality of second base frame to decrease tension on the plurality of second slats and (ii) moveable away from the base frame to increase tension on the plurality of second slats, and
• a second tensioner operable to adjust tension applied to the plurality of second slats by moving the second slat bar in a direction towards the base frame and in a direction away from the base frame.
