The Millboard Duofix Side Fixing Guide is a practical tool designed for installing decking boards with a discreet side-fixing method. Made from durable glass-filled nylon, the guide fits over decking boards within a width range of 145 to 200mm, ensuring versatility across multiple decking types.
On-site, the guide works in conjunction with Durafix screws and the supplied driver bit to align fixings accurately, control screw depth, and maintain a consistent 6mm gap between boards. This helps achieve a uniform and professional finish, particularly on composite and timber decking installations.
