Boss Clamp 4 Bolt Type, 4 Gripping Fingers

Use

• Bolts in Boss Clamps are designed to bend as they are tightened. This allows the clamp to conform to the hose outside diameter.
  
• Always tighten bolts to their specified torque value.
  
• Periodic re-tightening of bolts is required due to “cold flow” phenomenon present in all rubber hoses.
  
• Boss Clamps are for single use only! Once removed they are to be discarded.
