Marketing InformationHook-on straps are a great way to support stub-out water lines, whether they be for showers or bath tubs. You can combine our plumbers tape or pipe straps with our hook-on straps to have a full stub-out system installed. Our hook-on straps comes in both 18 and 26 in, ensuring that we've got the right size for many different lengths of space in between joists. There are also multiple punched holes through out the length of our hook-on straps to make their size more flexible.
