Constant Tension Bands are the ideal fasteners for hose-spigot connections which are submitted to extreme temperature changes, or which tend to "slip away" under pressure of the clamp. This version is pre-opened and pre-positioned on the hose. These spring band clamps are quick to assemble and easy to install and their integrated spring retaining mechanism provides a continuously readjusting dynamic tightening effect. They are available in band widths of 12 and 15 mm, and will accommodate nominal diameters from 13 up to 80 mm.
