Source of adjustable metal straps for mounting to large poles
Rain Jaudon:
Have googled adjustable metal straps, adjustable steel straps, and every other variety of pole mounting / speaker mounting search terms and turning up nothing but metal straps for wrapping pallets.
What is the proper term and where can I find them?
I have a pair of 50 lb speakers to mount to concrete light poles on a high school ball field. I'll have concrete anchors into the poles themselves but would feel more secure with the metal straps as a secondary attachment.

Pole straps?

Edit: Wrong link. I can't think of the name of the product I just used to do exactly what your talking about, but when I do I'll post it here.
Hal Bissinger/COMSYSTEC:
If it were me I would talk to the pole manufacturer before I attempted to drill into them for anchors. It's easy to compromise precast products in many cases if you don't know what you are doing and I don't think you want to be responsible for replacing the pole.
As for mounting hardware, I used to have a link but of course I can't find it. That also could be something to ask the pole manufacturer.

Simon Lewis:
The term I'd use is "steel banding".

Hi,
If I understand your requirements, over here they are called column brackets or clamps. Might be a different name in the USA. Doughty either stock or will fabricate what you want. They have a shop in TN, which covers the USA.

Also have a look at the clamps section.
Iain.
