Slide Series · Made in Rotterdam
SlideUnder Crossbar Elite (Surface)
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, printed in carbon-fibre reinforced PETG-CF (glass-fibre for White), 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.
Why Elite
- Heat-stable to 80 °C. Holds its shape on sunlit desks and in warm rooms.
- Stiffer under load. Fibre reinforcement means it won't sag or creep with your Surface seated, day after day.
- Daily-use tough. Higher impact resistance than PLA. It shrugs off reseating, knocks, and bumps.
Slide your Surface in, connect one cable, and get the full 40Gbps USB4 bandwidth and USB-C Power Delivery of your Surface, hidden out of sight.
Compatible with the Surface Laptop 13.8" (7th and 8th Edition), which share the same chassis. Printed on demand in Rotterdam in Carbon Fibre Black or Glass Fibre White.
Standard variant fits a desk edge-to-crossbar distance of 23 cm and a crossbar height of 5 cm. Not your size? Select the custom variant and enter your dimensions above before adding to cart.
Photos currently show the MacBook version of the Crossbar. Real-life photos with the Surface Laptop will follow soon.
