Worm drive hose clips

The worm drive clip does the holding a hose tail does not. The screw pulls the band in and the band presses the rubber onto the barbs. W1 grade: band, housing and screw are all zinc-plated steel.Choose on clamping range, measured over the outside of the hose once it is on the tail. Band width 9 mm for thin hose, 12 mm for thick or thick-walled. A wide band spreads the load and is slower to cut in.
