The bracket is good. Not impressed with the plastic thread insert at all. I ended up using actual sheet metal nut inserts instead of the plastic to imbed in the hole with epoxy.

Embed the plastic housing with nut inside into a concrete countertop. Once I started to fasten the nut inside would pull out of the plastic housing. I had this problem with 60% of them. I ended up using tapcons with the brackets from the PFUCCLIP.
