I would like to share my findings and usage, so this can be of use for You...
I use this size clamps to mount led lights or other effects on a speaker pole.
With this, you can mount some lights on the pole between f.e a sub and top speaker and create a fine looking and easy to setup system.
I mount 4 or 6 ( 2 or 3 on each side ) battery pars to the pole and no need for extra cabling: so it looks 'clean' and also a quick setup and tear-down.
