Ultra-thin protection for large laptops

The Rain Design keyboard cover measures .025 mm thick and fits 17.3 to 18 inch diagonal screens. A three-pack supplies spare layers for clinical, laboratory or shared-workstation environments. Transparent polyurethane preserves backlight visibility while blocking liquids and particulates. Each sheet is wipeable and reusable after cleaning with alcohol or water.

Replaces loose overlays that shift during typing

Earlier silicone sheets at .2 mm or thicker reduce key travel and trap debris at the edges. This cover bonds flat across the deck without adhesive, eliminating gaps where coffee, beer or milk can seep. The upgrade is worth it when a sealed, flat surface is required for infection control or clean-room protocols. Users who prefer a cushioned feel will not find it here.

Verify deck dimensions before ordering

The cover suits keyboards 16.54 to 17.32 inches wide and 8.27 to 8.66 inches deep. Measure the actual key area, not the chassis, to confirm fit. Touch ID and other capacitive sensors operate through the film. No additional software or calibration is needed.

Questions about this item

What keyboard width range does this 17.3–18″ cover fit?

The cover fits keyboards 16.54 to 17.32 inches (420 to 440 mm) wide and 8.27 to 8.66 inches (210 to 220 mm) deep.

How do I install the cover so it does not shift during typing?

Lay the 0.025 mm polyurethane film flat over the keys, align the edges with the keyboard deck, and press from the centre outward to remove air pockets.

How often should the cover be cleaned and when must it be replaced?

Wipe with alcohol or rinse with water whenever soiled; replace the cover if the film tears, loses adhesion, or no longer lies flat.
