Preformed Band Clamp, 4.50 Inch ID, 0.75 Inch Width, 0.030 Inch Thick

For this style clamp, the key fit number you have is the inside diameter of the clamp itself, which is 4.50 inch ID. It is meant to wrap a hose assembly at that diameter so you get a smooth, uniform clamping surface.

Locks in place with a single lever movement, no hammering, no crimping, and no special tools needed. That makes it pretty practical for field work where you're not set up with a full tool kit. The JS-type preformed design handles the locking automatically once you work the lever, so the install process stays straightforward whether you're in a shop or out on a job.

These Band-It clamps provide strong, vibration-resistant holding power once installed. You shouldn't have issues with them coming loose under normal operating conditions where vibration is present.
