2 x JCS HI-GRIP HOSE CLIPS SIZE 70 ZINC PLATED 50-70mm JUBILEE TYPE 3 CLAMP

Is the measurement diameter?

What's the width of the band?

will this fit to a 60mm hose pipe?

Do the clips open out completely to wrap around a joint? This is to mend a spade handle and I can’t slip it down over the handle.
