If your laptop will not fit in the Dual Vertical Laptop Stand (ST-ADVSM), the usual reason is a case on the laptop or the wrong slot, since the Dual Vertical Laptop Stand has two slots of different widths and is designed for a snug fit. The front slot is about 1.2 cm (12 mm) wide and the back slot is about 2.0 cm (20 mm) wide.

How to fit your devices in the Dual Vertical Laptop Stand

1. Place the Dual Vertical Laptop Stand on a flat, stable surface before loading it.
2. Use the wider back slot for your thicker device. A 16-inch MacBook Pro (M1 Pro or M1 Max, 2021) fits in the back slot without a case.
3. Use the front slot for devices up to 12 mm thick.
4. Remove the case from your laptop. The Dual Vertical Laptop Stand is designed for a snug fit, so cases are not recommended for the 14-inch MacBook Pro (M1 Pro) or the 16-inch MacBook Pro (M1 Max), which already sit tightly in the slots.
5. If you want to keep a case on, use a slim one. Thinner laptops such as the MacBook Air may fit with a slim case, and iPads fit with cases up to about 3 to 4 mm thick.
6. Lower the device straight down into the slot rather than forcing it in at an angle.
7. Keep both devices positioned evenly so the Dual Vertical Laptop Stand stays balanced. At about 312 grams, the weight of the stand helps prevent tipping when devices are seated evenly.
8. Place Mac desktops horizontally rather than vertically. Standing a Mac desktop upright in the Dual Vertical Laptop Stand can make the stand tip because of how the weight is distributed.
9. Route charging cables along the back of the Dual Vertical Laptop Stand so the cables do not push against your devices.
