• Pre-Opened Constant Tension Band Clamps
Pre-Opened Constant Tension Bands are the ideal fasteners for hose-spigot connections which are subject to extreme temperature changes, or which tend to "slip away" under pressure of the clamp. This version is secured by a small plastic clip. After slipping the clamp onto the hose, this clip can be easily removed by hand. Pre-opened, (and if desired, pre-positioned on the hose) these spring band clamps are quick to assemble and easy to install. 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.
