Bought from powerwatts last year for $56 or whatever they sell them for. If you’re doing powerwatts you more or less need these cleats. They’ve been used 7 times, and only indoors at powerwatts.
They’re missing two small bolts, which I found fine for powerwatts, but I’m sure any hardware store could help you out, or if it’s a point of contention on the sale I’ll just go get them.
