Broad Tip Clamps with hanging black glass beads have an adjustable pressure screw and rubber tips for a better grip.
To help navigate the world of clamps, Spartacus developed a pressure guide. The clamps are each color coded and numbered 1 (yellow), 2 (orange) or 3 (red), depending on the amount of pressure they apply. Adjustable clamps have multiple numbers, indicating their full range of intensities.
