Hopefully one of the installers or an electrician can offer some advice. I don't know the answer to the question.

We use a corner clamp, same idea though. As far as I know, our warehouse only buys DTV approved materials.

Looks good to me. I always scratch away the paint surface when I am attaching the ground clamp to the grounding source.

They are DirecTV approved. HSPs have a long history of hiring morons to be head QC'ers, and these idiots will declare something "not allowed" because some installer screwed up and they want to feel important. If you talk to an electrician, they will PREFER that you use these, as they don't want you messing around inside the box at all.

Also, these front-panel clamps have screws on the two outside holes that are designed to cut through the paint and dig into the metal. You don't have to do anything special; just tighten the screws, then tighten the lock-nuts.

Many other types of grounding equipment DO require scraping off the paint (ground straps are a good example), so do so when it makes sense to.

I am not a big fan of that type of clamps. They have a history of having a questionable electrical connection (if any) and typically are barely connected anyway mechanically. I would strongly suggest using a 'real' ground clamp to the electrical system's ground rod. Remember that each wire to the ground rod gets its own clamp. No sticking 2 wires into the same ground clamp. At about $3 each at Home Depot or Lowes, doing it right won't break the bank. And remember, if using more than 1 ground rod, they must each be bonded to each other (to ensure equi-potential) and that ground rods should have 8 feet of continuous ground contact (meaning an 8' ground rod should be just about all of the way into the Earth).
