The Column Tie clamps to the flange of a column. It accommodates a steel thickness from 6mm to 25mm and should be installed at 225mm vertical centres. Manufactured in lengths to suit the application, it can feature a drip for use across the cavity or a plain shank for installation back into the inner leaf. As standard, the clamp-on column tie is supplied right-handed as shown in the isometric product drawing below, but can be manufactured left-handed on request.
