Product Description

Heavy Duty Double Bolt Double Band Clamp (HDDD)

Product Description

Double band makes the clamp a very strong heavy-duty clamp.
Double bolts provide a high clamping force.
Two Channel Bridge under the bolt provides 360 degrees of contact on the hose helping to distribute clamping force evenly to prevent leaks.

Double Bolt Double Band Clamps are suited to applications where there is a requirement for greater strengths due to higher pressures
