A ladder clamp used in scaffolding is a safety fitting designed to secure a ladder firmly to a scaffold structure. It is usually made of steel and consists of two clamping sections that fasten the ladder stiles to a scaffold tube. Once tightened, the clamp prevents the ladder from slipping, shifting, or falling during use. This ensures safe access to different working levels of the scaffold. Ladder clamps are commonly used on access ladders in scaffolding systems to improve worker safety, stability, and compliance with site safety standards.
