This wolfcraft 700 piece joiner set for concealed fastening allows you to fasten the deck boards invisibly on the underside of the boards. You can be confident of the result and meet the highest standards.

• No visible fastenings for high-end look: This set is perfectly suited to fasten the deck boards invisibly on the underside of the boards. This means no more sheared screws or cracked deck boards.
• Optimally installed deck boards: The joiners create distance between the deck joists and deck boards. This protects against waterlogging, ensures optimal ventilation and means uninterrupted enjoyment of your wood deck for many years to come.
