Could somebody with one of these pads do me a favour, and measure the width of the flat part where the kick pedal clamps?

I have a Sleishman Twin I'm planning to use, but the clamp is designed to hook underneath a hoop like you see on an acoustic kick drum.

You can see it in the image linked below:

I think attaching it to that lip will work, any opinion welcome.
