Processing instructions:
Groove ungrooved planks with the milling machine along the entire length or with the lamellar joint cutter at specific points at the intersection with the substructure. Slide the SB-U2 system fastener into the groove and fix it in the substructure using the bolt with a screw. Do not tighten the screw yet! Slide the next board into SB-U2, insert and fix another connector. Then fasten the previous board by tightening the screw. The start connectors are used for the start and end boards. If the lower groove cheeks are less than 11.5 mm thick, the predetermined breaking point of the spacer bolt breaks off when the screw is tightened. This sinks into the connector and the floorboard is reliably clamped.

Characteristics:
Glass fiber reinforced polyamide. Permanently dimensionally stable. Immutable. Weather and moisture resistant
3 in 1 Invisible screw connection. Constructive wood protection. Spacers between the planks
Bolt with predetermined breaking point. Variable clamping range for lower groove side thicknesses from 5.5 to 11.5 mm
Start connector for invisible attachment, even in the edge area
