Abstract: A universal cell phone security band for displaying cell phones of various sizes includes a band that is placed around the phone. The band has a first end and a second end with notches extending from its edges. The band's second end is received in an adjustable slide at a slot including a wide portion configured to receive the notched second end and a narrow portion configured to receive the portions of the band between the notches. The adjustable slide also has an opening that is configured to receive a threaded connector that is disposed on the band's first end. The opening and the threaded connector are secured with a security-type fastener having a recess that requires the use of a tool other than a traditional flathead or Phillips head screwdriver to rotate the security fastener. A cable can secure the universal security band to a display.
