Ideal Tridon's 3/4" (19mm) wide 30021 Channel Bridge T-Bolt clamps provide uniform sealing pressure for a positive, reliable seal. Designed for use in high vibration and large diameter applications common in heavy trucks, industrial machinery, offroad equipment, agricultural irrigation and machinery. Features a 3/4" wide 300 stainless-steel band, bolt, and welded construction for reliability. Fully 300 Stainless Steel parts enhance the corrosion resistance of the product over the 30020 series

These T-Bolt Clamps also have a channel style bridge which spreads the load more uniformly around the hose, improves the sealing and protection around the hose and prevents localised pinching or deformation.
