The special wedge will hold firmly by just tightening it gently. This makes it faster to mount, easier to handle.

Some nice details:
The C-Wheel will hold the C-Reflector firmly up to 3G force, so you can mount them on cars or rig them on wind exposed areas.
It has special sliding plastic, so exchanging the C-Reflector after it has been rigged will go easily and silent.
A special plastic ring within the C-Wheel will prevent the Wheel from jamming when opening up the C-Wheel completely.
The C-Wheel has a safety wedge that will break at 0.5Kn. (So if the stand falls over, the wedge will break, the reflector will be unharmed.)

You can replace the C-Wheel with an aluminium  rigging wedge if you don’t want the safety wedge. (Like rigging high above people for long term jobs)
