Vice grips (single-action) - having one fixed jaw against which a second parallel jaw is tightened. The position of the fixed face may be adjustable to accommodate differing specimen thickness. They may be manually screw-operated, or pneumatic.
Vice grips (double-action) - having two adjustable parallel jaws to enable in-axis alignment of the test specimen. They may be manually screw-operated, or pneumatic. Vice grips are typically used in pairs and are available with an extensive selection of interchangeable jaw faces and sizes.
Vice Grips are an ideal ‘general-purpose’ grip for testing thin sheets, films, foils, tapes and various plastic, metal and textile fabrics.
