About Measuring Hose and Tube Clamps
What's the best way to determine the clamp size you'll need? Simply measure the outside diameter of your hose with the fitting installed. Some clamps accommodate a range of sizes, so be sure the size you need falls in the middle of that range.

Duct Hose Clamps for Spiral Duct
Also known as bridge clamps, these worm-drive clamps align with the spiral support on wire duct hose to provide a tight seal.
When looking at the end of your hose, a right-hand spiral twists away from you clockwise; a left-hand spiral twists away from you counterclockwise. Clamps have very good corrosion resistance. Do not exceed the maximum torque or clamps may be damaged.
Note: When choosing a clamp, measure the outside diameter of your hose with the fitting installed.
