I was wondering how often do you find use for the above? (low voltage applications).
I'm asking because we recently did a wiring job (all Cat6) and the customer insisted on them on all vertical runs and at the horizontal consolidation points on each floor. In my view it was a bit of an overkill.
There were a lot of runs, but their offices spanned only 4 stories, the longest run was barely over 75 feet (wall plate to 110 block) and the wiring was supported in raceway/conduit throughout.
I thought the tensions could be handled very adequately without grips + strain reliefs. These things were not exactly cheap relative to the cost of wire used.
Is there something I am missing here? I just would like to know the memberships' opinions and practices.
