QUATRO 65 | Hidden deck, panel and board connector incl. 500 CS-screws

The QUATRO 65 is a connector for decking boards and wall panels. It is mounted easily and is non-visible from the first board up to the last. As a result, the connector offers a perfect appearance and high level of security.

QUATRO 65 is easy to handle for professionals, as well as for DIY home improvements. It can be pre-mounted and the boards or panels are quickly fastened on-site using the connector system.

The greatest benefit of this connector is that it allows the natural movement of the wood. Rainwater is diverted, and as a result the durability of the coating and construction is extended.

The QUATRO 65 is fastened on the bottom side of the boards or panels. The elements are then screwed onto the joists. In case of very hard wood, the screw holes should be pre-drilled.

The mounting template enables an even and precise adjustment of the width of the joint. The proper spacing can also be adjusted using the measured grooves.

  • Concealed from the first board to the last
  • Constructive wood protection against moisture
  • Allows expansion and contraction of wood boards
  • Optimal rear ventilation through spacing
  • Can be used for timber facades and formwork, for which rear ventilation has been implemented
  • Easy installation with mounting templates
  • UV and weather-resistant fiberglass reinforced plastic.

Tips:

  • Even the best connecting system cannot offset poor quality of some timber. Please ensure that the timber is dry; particularly, avoid timber from the core and spiral-grained boards.
  • Recommended length of the boards: maximum 3 m (9.8 ft.).
  • Recommended for spacing no smaller than 7 mm between the boards and the joists
  • You may pre-drill, particularly with hardwoods, such as oak.
  • Follow the installation instructions of your timber supplier.

Z-DECK | Deck fastening, stainless steel

Z-DECK Hidden Deck Fastener

The Z-DECK is a concealed, very strong stainless steel deck connector. Mounting is made easy through screwing horizontally in the board and vertically in the construction below. Through the special shape of the Z-DECK, the connector allows the wood to shrink and swell, and fixes the boards stronger than a normal screw from above.

Tests have shown a great performance of the Z-DECK with hardwoods, as well as tropical woods. The Z-DECK connector is concealed, but every board can be removed individually.

The Z-Deck connector has a special hook that hooks into a groove on the narrow side of the board. As the connector is hooked and screwed to the narrow side of the board, the connector with the board will be screwed to the joints below. At the same time, the screw allows shrinking and swelling between 4-6 mm. The connector is hidden but each board can be removed individually.

  • Concealed from the first board to the last
  • Very robust and can be used even for beach and boat docks
  • Boards can be quickly and individually replaced
  • Optimal wood protection through self-cleaning joint design
  • More solid than visible screw connections from the top
  • Increased security against twisting of the boards
  • Connectors and screws are made of quality stainless steel
  • Exceeds the requirements of Holzforschung Austria

Tips:

  • Even the best connecting system cannot offset poor quality of some timber.
  • Please ensure that the timber is dry; particularly, avoid timber from the core and spiral-grained boards.
  • Recommended length of deck board: max. 3 meters (9.8 ft.).
  • Recommended spacing: starting at 7mm
  • Pre-drill, particularly with hardwoods, such as oak.
  • Follow the installation instructions of your timber supplier.
