When you purchase a Nack Desk it will come with Bin Lids and an Access Slider. Find these bundled or packaged together and carefully remove the packaging.
These parts are made of acrylic. To protect the plastic's finish we left the protective film on each side. All you need to do is peel off the protective film and you've got parts!
Slider Insert
Do this step after attaching your legs and setting the desk upright.
Find the finger hole on the slider. Facing the desk, you'll want the finger hole on the left. It takes a little finagling but you'll twist the slider panel and insert to the right until you can get it to rest flat inside the desk.
Using the diagram below you can see that the slider has a pre-cut pocket for it to slide back and forth easily on. Once you've aligned it in the pocket you are ready to use!
We prefer the frosted side of the acrylic facing down but that's up to you.
