Description
DUO-System – Sample Pack
The DUO-System provides the optical qualities of traditional frame joints while being engineered in an innovative manner for fast processing and application. For example, the DUO 100/15 is an ideal frame connector for beds, and, like all KNAPP connectors, is non-visible, can be disassembled, and self-tightening. Beds made with the DUO 100/15 provide the perfect finished look with no visible fastener parts.
The Duo system is non-visible as it is installed in a mortise or rebate using our Routing Jig with a depth of 13 mm and milled either into the end-grain or face of the wood component. The DUO-System connector consists of two identical connector parts, made of high strength blue-galvanized weather-resistant steel, and is manufactured in Austria.
The choice of the correct DUO connector size depends on the used timber dimension. The milling operations can be made optionally with a hand router or a CNC. It is so quick and easy to assemble that even the end-user can do it, and with 8 different sizes, you will be sure to find the exact size you need.
Features and Benefits:
- Fast assembly
- Efficient and very good to use in production line manufacturing.
- Components are simply hooked together in seconds
- Reduces labor and equipment cost
- Efficient: High degree of pre-manufacturing.
- Components can be transported and simply assembled on site.
- Non-visible connector
- Appeals to the architect and customer
- Concealed
- Self-tightening
- Adjust with the included pan head screw to desired tightness
- Can be disassembled and reassembled
- Versatile
- The wood component can shrink and swell, while the joint can be adjusted and re-tightened via the screws of the fastener.
- Safe and tested by HFA (Holzforschung Austria)
Tips:
- Perfect for industrial manufacturing with CNC
- For handheld routers, use the Routing Jig for a perfect installation every time.

Load Values
Note* The load value refers to the transverse force in the insertion direction.
Details of the stress values are of the certificate of Holzforschung Austria from 02.11.2000 and the current KNAPP catalogs. For commercial use of the DUO-System, according to Ö-Norm M5027, CS-screws (5×40, 5×60, 6×40, 6×60 mm) should be used.

Installation
(View and Download Instruction Manual)
Steps:
- Use the KNAPP® ROUTING JIG to perfectly align and mortise both workpieces 13 mm deep using our Ø 15 x 25 mm TCT Slotting Cutter.
- Set the DUO-System connector half into the mortise and predrill holes.
- Attach one DUO-System plate with the screws provided
- Lay the second plate over the first (see picture below) and screw in the pan head screws until they are snug against the second plate. (this will set the correct depth of the pan head screws and ensure a tight fit during final installation)
- Install second DUO-System plate with the screws provided
- Attach workpiece using a rubber mallet
Tips:
- Use a hand router or CNC machine with a Ø 15 x 25 mm TCT Slotting Cutter to cut the mortise or rebate.
- The joint is always tight, as the connector snaps together in a dovetail-like manner. Still, the fasteners allow the natural shrinking and swelling of the joints and are adjustable if needed.
