They're good, but to be honest the screws should be a bit longer. 1/4 inch is probably enough. However, if you bend the part that goes over the channel a little, you'll obviously have to bend it a little to get over the edge, but they will snag. I need six for cameras and solar panels and am happy with the price and build quality.
