A BRC clamp, also called a plank clamp, is a steel clamping device used in scaffolding to secure scaffold tubes, planks, or platforms to structural elements. It is designed to hold scaffold components firmly in place without drilling, providing a stable and rigid connection. In practical use, BRC/plank clamps are commonly employed to attach scaffold planks, ledgers, or brackets to walls, columns, or existing structures, ensuring that the working platform remains safe and level. The clamp grips the tube or plank securely and is tightened manually, making it quick to install and reusable.
