BumpTech Dell 3180 Case (Clamshell) Protect the Dell 3180 without breaking the bank. Our new BumpTech case enhances traditional hard clamshell cases with a shockproof bumper that wraps around the edges. The case is thin enough to allow the Dell 3180 to fit into any charging cart, provides excellent venting to keep your device cool, and gives you easy access to all ports. The BumpTech case features a transparent panel on the bottom to add device identification including asset tags, school logos, photos and more!
