Slide Series · Made in Rotterdam
Designed for desks with a crossbar.
The SlideUnder Crossbar Standard brings the full SlideUnder experience to desks where clearance is limited. 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 Surface in, connect one cable, and get the full 40Gbps USB4 bandwidth and USB-C Power Delivery of your Surface, completely hidden from view. Built on our reinforced Surface frame: a thicker mount with washers for overtightening protection.
Compatible with the Surface Laptop 13.8" (7th and 8th Edition), which share the same chassis. Precision-printed to order in Charcoal Black PLA in Rotterdam.
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.
Desk in the sun or looking for white? SlideUnder Crossbar Elite is printed in heat-stable PETG-CF, in Black and White.
Photos currently show the MacBook version of the Crossbar. Real-life photos with the Surface Laptop will follow soon.
