Sometimes the mason’s platform is adjacent to an opening in the wall, such as a large window opening or between tall columns. This device attaches to two boards anywhere along the length of the platform. It gives you a Guardrail Post socket identical to the ones on the laborers’ side of the scaffold. Can be used wherever you have 2, 3, or more boards.
There are holes in the flanges to secure them in place with nails or screws.
