Clamex S-20: Detachable furniture connector for the 4 mm groove

Lamello AG Stand: D20

Clamex S-20
Like every Clamex connector from Lamello, the Clamex S-20 is also detachable and is powerfully connected to the counterpart via a lever. The machining for the connector can be undertaken according to the proven Lamello system with the Classic X or the Top 21 biscuit joiners. The connector halves are anchored in the groove with two screws each and ensure a strong hold. The small 6 mm access opening for closing and opening the connector offers an aesthetic finish, whether for corner, surface or frame connections. A new feature of the Clamex S-20 is the narrow design, which allows installation in very thin materials. Mitre joints are possible from 14 mm material thickness or butt joints with installation into the edges from 8 mm material thickness. Like every Clamex connector, the Clamex S-20 can be used for angle connections from 30º - 180º. The system includes a drilling jig, which is included in every sales unit. This enables precise positioning of the drill, even at acute mitre angles.

Use with any grooving machine – anywhere
As the Clamex S-20 is based on the 4 mm groove system, the groove can be cut into the materials with any commercially available groove cutting machine. This makes this connector an excellent choice if, for example, no Zeta P2 is available on the construction site. The Clamex S-20 can also be used to create precise and attractive furniture joints on site and thus to install fillers or entire cabinets. Not only on the building site or in the workshop, but also for hobby cabinet makers with their own biscuit joiner, there are now (almost) no limits with the detachable Clamex. Typical applications in furniture or interior construction are cupboards in roof slopes, cabinets or prototype construction.
