These clamps are smooth on the inside and will not bite into silicone like worm gear clamps.
Clamping ability is over 20 times greater than worm gear clamps.
Bolt is easy to tighten since it is out away from the clamping surface.
Clean, shiny, and professional looking - show quality clamps.
Do not get dirty as easily as worm gear clamps, and are easier to clean.
