These conversion column brackets are designed to convert standard columns to the 'Hockey Stick' style. They are available with a choice of three jointing systems, the slip in and scissor methods being virtually seemless. The slip in system requires the column to be drilled and threaded for two M10 securing screws. For the scissor joint we recommend the fitting of a M4 S/S self tapping screw 50mm below the joint into one of the scissor legs to prevent turning.
