This is a replacement pad for the Festool Quick Clamp.
The original one has a little flex in the material to bend and clip in place, the filament is more rigid so it will be a tight fit.

I would recommend firmly fitting the back end in and then clamp down using a board to snap in in place. Feel free to sand down one clip so make it a little smaller.
