E20 is a self-clamping element and can be used with any Lamello biscuit joiner. The E20 is driven into the 4 mm groove using a hammer.
During insertion, the curved ridges on each side of the connector hold in the groove and clamp the workpieces together. E20 serves as a perfect glueing aid in the workshop or on site

E20-L is suitable for surface joints such as picture frames, plinth or panel extensions.
E20-H is used in the edge and serves as a plinth connector.
