Connect two adjacent panels with a panel connector. Set the two panels next to one another, with the panel connector in the middle. Set the panel connector top draw block on top of the top wedge block.
Make the panel connector wider by using the Allen wrench to turn out the Allen screw in the top draw block. Now, move the second panel to position its top wedge block under the open half of the top draw block.
Use the Allen wrench to tighten the Allen screw in the top draw block of the panel connector.
Add a panel connector to position two panels that form a 90-degree angle, as another way of assembling the cubicle. Position the connector's top draw block on the first panel's top wedge block.
Use the Allen wrench to loosen the Allen screw in the top draw block, and then tighten once the connector's bottom draw block clears the bottom wedge block.
Loosen the Allen screw on the connector's top draw block, lift it up until the panel's top wedge block is under it, and then tighten the screw.
