To install the B-2U rail on the Basis rail, do the following:
1. Choose the most suitable place on the Basis rail.
2. Decide which method you will use to install the rail. That is enough to use only one mount to install the rail, but an installation of both elements is also possible.
3. Align the openings on the Basis rail and on B-2U rail.
4.1. If you use an oval mount: install the oval mount on B-2U rail. The screw on the mount must not be tightly tightened so that the mechanism can freely rotate in the Basis rail. Install B-2U on the Basis rail, so that the oval mount fits into one of the openings on the rail. Use a screwdriver to turn the oval mechanism clockwise until it stops. The oval should rotate 90 °.
4.2. If upper rail is installed on lower rail, you may place a B-2U rail in the place of their connection by M5x9 screw.
