The pre-engineered RICON® EAR (with Rampa Insert) series allows for simple and fast joining of beams and is used mostly to in joining vertical and horizontal mullions in wood curtain walls. It consists of two identical metal connector plates that hook into each other in a dovetail-like manner. Typically, one of the plates sits in a recess and the other is plainly screwed on the surface of the beam.
For easy installation, KNAPP® also offers Drilling and Routing Jigs as well as a Mounting kit. The connector plates on the end grain are installed with self-tapping 5×80 mm and 8×80 mm SC-screws and on the side grain with self-tapping 5×50 mm and Rampa insert M8x18 with CS-screws M8x25 for all other sizes. The 8×80 mm and M8x18 CS-screws have an integrated stop, thus, the screw sits above the connector and engages with the dovetail receiver socket of the other connectors when hooking them into each other.
An optional Locking clip can be installed to latch the connector, additionally, the locking clip can be removed later on. The RICON® can be installed fully concealed or visible and can be used with timber widths as little as 50 mm. RICON® is available in three versions, Single Connection (EA), Double Connection (DA) and Rampa insert (EAR), and with this in mind, each version has six sizes 60/40, 80/40, 100/40, 120/40, 140/40 and 160/40.
