Exclusively designed for Surface Pro (not compatible with Surface Pro X) and Surface Go to provide professional-level security and superior device engagement. Non-invasive locking technology delivers an easy-to-use security solution that requires no device modifications, preserving the Surface Pro's hardware warranty and aesthetics. The strong lock head is tested for torque/pull, foreign implements, lock lifecycle, corrosion, strength and other environmental conditions, meaning it meets Kensingtons industry-leading standards for tamper resistance, reliability and durability. The 1.8m (6ft) plastic sheath-covered carbon steel cable resists tampering and offers the same level of cut-resistance and theft-deterrence as thicker cables. Register & Retrieve, Kensingtons free online program, provides quick, secure code registration. With a five-year warranty, you can rest assured knowing you're covered by Kensington, inventor and worldwide leader in laptop security locks.
