This 3-pack of tempered glass screen protectors are precision cut to provide full screen protection for Honeywell Dolphin CT40 handheld barcode scanner mobile computer. Specifically designed for CT40 and highly compatible with it. 3-pack is more cost-effective. Please check the device model carefully before ordering. Thin and tough tempered glass protective film allows for precise touch sensitivity and reacts like a barcode scanner's own screen, ensuring every touch is transmitted accurately. Ultra-high transparency produces vibrant colors, ensuring you see all screen content clearly and sharply. This protector is made of high-quality tempered glass, and the 9H surface hardness provides your screen with strong impact protection. It's 2x stronger than regular screen protectors and lasts longer. It has highly shock absorbent, protecting your barcode scanner screen from scratches, drops and minimizing the risk of display breakage. This protector applies easily and without bubbles. The special glueless adhesive adheres the protective film to the screen perfectly, leaving no sticky residue after peeling off. The special low-tack adhesive takes a while to fully adhere around the edges, and the air gap disappears after about 2 days of normal use.
