This thing is amazing, perfect set of rafters for a novice self-roof builder
Great piece of kit.
Very well made and well finished.
Easy and quick service from ordering to delivery.
Works as described, you loose the width of the stop on your ruler, well made.
Well made and heavy square, the anti tipping does not work as described, the black block is to heavy and the square falls off the material due to the weight of the block.
