SlideUnder Crossbar Elite (Macbook)
Main description
Designed for desks with a crossbar. Built to take the heat.
The SlideUnder Crossbar Elite brings the full SlideUnder experience to desks where clearance is limited — now printed in carbon-fibre reinforced PETG-CF, the most heat-stable, rigid mount we make. Sloped cradle arms let the SlideUnder tilt past your desk's crossbar, so nothing gets in the way of a clean, hidden install. Improved 4-screw mount. Smarter geometry.
Slide your laptop in, connect one cable, and get up to 80 Gbps bandwidth (Thunderbolt™ 5 compatible) and up to 240W charging. All tucked out of sight. The carbon-fibre reinforcement keeps the mount dimensionally stable under load and warm cabling, so it holds its shape through years of daily use.
No bulky docking stations. No cable clutter. Just a clean desk and a MacBook that's always charged and ready.
Standard variant fits a desk edge-to-crossbar distance of 23 cm and a crossbar height of 5 cm. Not your size? Order the custom variant and mail your order number + dimensions to support@dockedbydesign.com — we'll take it from there.
Note: 80 Gbps / 240W reflect your MacBook's own capability. On Air and Neo, Elite is the carbon-fibre material upgrade — not a speed or charging boost.
