Product reviewsBlack G-clamp Mounting Hook Straight Fits up to 50mm Bar Round or Square Strong

Certainly Heavy duty, but do they grip?

I bought these to hold a couple of fairly light-weight slim LED par cans on to PA speaker poles.

The lights attach to the clamps fins and the clamp does look ridiculously heavy duty. However, they don't like gripping the poles; Standard heavy-duty speaker poles. it is difficult to get them to grip and when they do, they are not secure.
