How do I know if my BookArc is compatible with this insert?

Check the inserts that came with your stand. If they are labeled with letters (A, B, C, etc.), you have the current version and Insert E will fit. If your inserts are numbered (1, 2, 3, etc.) or if you have a BookArc mod, this part will not work.

Will this fit the 2020 MacBook Air?

No, this insert is sized for the 2018–2019 MacBook Air with Retina Display and the 13-inch MacBook Pro from 2020 only. Other models require different inserts matched to their specific thickness and dimensions.

How do I install the insert in the stand?

The insert slides into the arc cradle of the BookArc stand without tools. You simply remove the old insert if one is present and push the new one into place until it seats securely.

BookArc Insert E for 2018–2020 MacBook Air and Pro Models

Most vertical stands use foam or adjustable clips that wear out or slip over time. The BookArc system relies on precision inserts machined for each laptop generation, so the cradle holds firmly without moving parts or padding that compresses. That approach means you need the exact right insert—but it also means a stand you bought years ago works perfectly with a replacement part, no adjustment or guesswork required. Worth it if you value a clean desk and already own the stand.

Good gift when

Anyone who upgraded their MacBook and needs a matching insert for their stand
People with a 2015-or-newer BookArc but the wrong insert for their current laptop
Buyers of secondhand BookArc stands missing the correct sizing piece

Skip it if Only works with the 2015-and-later BookArc stand that shipped with letter-labeled inserts; if your stand came with numbered inserts (1–8) or is a BookArc mod, this part will not fit

The details

This insert extends the device compatibility of your existing BookArc vertical stand. Sized specifically for the MacBook Air with Retina Display released in 2018 through 2019 and the 13-inch MacBook Pro from 2020, it swaps into the cradle arc in seconds and holds the laptop securely upright in clamshell mode.

The part works only with the current-generation BookArc that shipped from 2015 onward—the version whose original inserts are labeled with letters A through H. It will not fit older stands that came with numbered inserts or the BookArc mod.

Each insert is machined to match the thickness and footprint of a particular laptop generation, so the stand grips without wobble and clears ports without pressure. If you've upgraded your machine or bought a used stand without the right insert, this part restores full function. Available in silver or space gray to coordinate with your device finish.
