I bought this to go with my larger combi square.
Works great
Works very well ,with the mk 2 ruler.
Very good quality 👌
This was something I was looking at for a while and wish I'd gotten it sooner. There is a learning curve with the initial setup and making both the same length but now it is much easier. The only issue I had was with one of the bolts almost instantly stripping when initially putting them together but was sent a new set without any questions when I emailed in. Couldn't be happier with the experience and product.
