    Bought one of these Squares last year. What an excellent piece of kit it is. Solid and well engineered. Easy to set up and very accurate.
    The service and communication where second to none and the delivery time was really quick.
    I would highly recommend.

    Thank you

    I was hoping this was going to be a good addition, but it’s even better than I thought it would be. It’s absolutely spot on and quick and easy to use. Well worth the money

    This is my second FC rail square from Frank as the hybrid is living on my Festool rails and i wanted a second for my Mafell rails, having an engineering background you can clearly see the quality of this square in both the manufacturing and the design. I have had another rail square previous to my 2 x FC squares and these are by far the best. Also I would like to say the after sales service is excellent. if you are looking for a rail square look no further this is all you need.

    These are fantastic squares I personally bought one of the originals and then purchased another one. And another for one of my fitters and from there on fitters that work for me have also ordered them as well as other tradesman who come across us using the squares. Cannot go wrong, they are the best on the market much better than the imitations.

    I was originally taken back by the price and hesitated for quite a while but decided to purchase one recently. I was cautious to manage my expectations but the guide rail square works incredibly well! Tested it after the first few cuts and all the cuts were spot on! Thank you for all the customer support and overseas shipment!

    Just ordered this one from Frank after chatting to him through messenger about the tolerances I can expect from this square. Very excited to get it and put it to some good use. It’s the most accurate rail square on the market. Great service!

    had a mk4 and when I changed to mafell rails I upgraded to this with bench dogs and am blown away, much better with the full lip and the ability to use dog holes for cuts too!
