"Just read the other reviews for this product. One of the reviewers claims to be an electrician, so I am wandering how could he/she give this product a rave review. These clip in blanks are so easy to pull off leaving a child to very easily put their finger directly onto the bus bar inside. Zap.
I quite often find consumer units with these blanks missing. I always use the full din rail mounted blanks. Much much safer."
