Functions the same as a standard Hose Clamp, however rather than needing to find a screwdriver (or dime!) for every adjustment you can easily tighten by hand.
As an added bonus, this also has a significantly smoother inside to the stainless steel clamp, which will not tear up your tubing nearly as much as a standard hose clamp!
Ideal for situations where you need to remove tubing from fittings to sanitize.
