Scaffolding board retaining clamps, also known as board clamps or board brackets, are used to secure wooden planks or boards to scaffolding poles. They are typically made of steel and have a surface treatment of electro-galvanized or hot-dipped galvanized, which helps to prevent rust and corrosion.

To use the board clamps, the wooden plank or board is placed between the two halves of the clamp, and then the clamp is tightened onto the scaffolding pole using the bolt. The clamp securely holds the board in place, preventing it from slipping or moving during use.
