Product Description

StepLess One Ear Clamp (OES)

Product Description

The StepLess design ensures uniform compression with 360° consistent surface pressure.
The clamp ear allows adjustable surface pressure, and the dimple increases clamping force, providing a spring effect that compensates for changes in diameter due to thermal expansion.
The narrow band concentrates the transmission of clamping force and reduces weight.
The mechanical interlock of this clamp keeps it securely closed and provides better corrosion resistance than a spot-weld.

Material, clamping range and your logo can be stamped on the band.
