Metra HWP-0001

The opposite side of the picture shown.

Should be the flat side. The "raised" area should point away from the work.

I inserted the screw on the side that was indented inward. It worked fine.

This was a while back that I had used these...however if I'm not mistaken one side was flat while the other had a small opening. I used the open side figuring it would be a littler easier and having that screw drill through the solid just made me feel it was a bit more secure. Also while installing the speakers I noticed I had to make new drill holes in the door panels not for all sides of the speakers just one or two so again it just I guess seemed to make more sense to have the opening on the clips face inside the car to wear the screw would enter that first. Let me say this I'm no expert however im running a 15" L5 at 700 RMS and shakes the whole SUV and I've had no issues with these clips failing the way I secured then...so thats some good news :)
