Product Details:

CRL Standard Spring Clamps have a modern design that minimizes the spread between handle ends, and makes the "Grip" more comfortable for the user. At full opening, the point of pressure remains at the jaw tips. Heavily plated steel clamps have smooth, bright finish to resist corrosion. Deluxe clamps have poly-coated tips and grips to add comfort for the hands and protection from the metal tips for the work. Excellent for use on surfaces that are easily marred or scratched. Three sizes available in either standard of deluxe type clamp.
