lock for stair squares

The turnbuckles can be used to securely connect the brackets together. You can adjust the step height and width on each bracket. You do not need a paper template or an angle board. Place the adjusted marking gauge on the raw stringboard. You can see the shape of the raw stringboard and the curve of the stringboard. By moving the angles on the raw stringboard, you achieve the best possible utilization of the stringboard wood with regard to knots and cracks.

The angles have a millimeter scale on both sides. Locks and brackets are made of high-quality stainless steel.
