For rapidly and rigidly clamping of temporary concrete column formwork the use of column clamps is standard practice throughout the building industry.Column Clamps are interchangeable which allows for narrow, rectangular, square or polygon columns to be clamped. The punched slots are staggered and lap each other to provide infinitely variable adjustments to cover all sizes of columns.Column Clamps save time and labour by reducing time taken to fit and dismantle the normal timber type clamp. This also reduces timber wastage. Only a hammer is required for speedy fixing of the Column Clamp Wedge.
