The Horizontal Cuplock ledger is a type of ledger used in scaffolding systems. It is a strong and versatile piece of equipment that is used to support the horizontal members of a scaffold. It consists of four cups (also known as ledger blades) that are connected by four pins. The ledger is then connected to the vertical members of the scaffold with adjustable couplers. The ledger can be adjusted to accommodate various lengths and heights of scaffolding, allowing for more flexibility in the scaffold system. The Horizontal Cuplock ledger is a reliable and cost-effective way to create a safe and secure scaffold.
