An isolator mounts a first device, such as hard disk drive, to a second device, such as a computer. The isolator is received in a hole defined in the second device for supporting the first device. The isolator includes a cylinder having first and second ends connected by a circumferential outer surface. The cylinder defines a central bore having an inner surface. A flange is formed on and around the first end of the cylinder. A plurality of first ribs is formed on the inner surface and extends in an axial direction of the cylinder. Each first rib has first and second end sections respectively extending on an outside face of the flange and the second end of the cylinder. A plurality of second ribs is formed on the outer surface and extends from an inside face of the flange whereby the second ribs and the first end sections of the first ribs are located on opposite sides of the flange. The second ribs alternate the first ribs.
