ABSTRACT:
An adjustable, elastic wristband for dissipating the buildup of excess electrostatic discharge from an individual. The wristband has two straps or strap sections, one electrically insulative and the other electrically conductive, and at least one of the two straps or strap sections being elastic. A connector case provides the electrical connection between the conductive strap and a conductive grounding tether. Various clasps are used to adjust the insulative strap or strap section. In each of the disclosed alternative embodiments, the wristband may be adjusted for comfort without requiring trimming of the excess strap material which is pulled through the clasp, and without otherwise exposing any conductive portions of the wristband, since the excess adjusted material is electrically insulative and thus may be left dangling.
