I was wary after seeing another review. But then I came back and ordered it anyway. I have reviewed high resolution product photos from other vendors and can confirm this is what they all sell. Maybe another reviewer has an older model. I put this spacer in and filled one half with 5lb nuts and bolts - it buckled a bit but showed no signs of failure. I didn't use glue, just stuck them in. There is nothing more to say about the piece of plastic. but yes it fits and yes it is quality.
