ABSTRACT:
A brace lock on a scaffold for releasably engaging a perforated end of a brace. The lock comprises a pin means with an end attached to the scaffold and a free end. The pin means has a thickness and contour which permits the perforated end of the brace to pass over the pin means. The pin means includes an offset so that when the end of the brace is positioned near the attached end of the pin means, the end of the brace will not slide to the free end of the pin means unless the end of the brace is raised upwardly over the offset. The lock also includes a latch means releasably securing the end of the brace when the end of the brace is positioned near the attached end of the retaining pin means.
