To Install the B-2 Rail on the Basis Rail:

1. Select the most suitable position on the Basis rail.
2. Choose the preferred installation method. Although one mount is sufficient, installing both is also possible.
3. Align the openings on the Basis rail with those on the B-2 rail.
4. If using an oval mount: Attach the oval mount to the B-2 rail. Keep the screw slightly loose to allow the mount to rotate freely in the Basis rail. Place the B-2 rail on the Basis rail so the oval mount fits into one of the rail openings. Use a screwdriver to turn the oval mechanism clockwise until it stops; the oval should rotate 90°.
5. If mounting the upper rail to the lower rail: Place the B-2 rail at the connection point using an M5x9 screw.
