Step by step using 2400 mm long Linear Feltfon Ribs.

1. Suspend the Nonius ceiling hangers from the ceiling.

2. Use the adapter NONIUS-CD to connect the BASE-CF profile to the ceiling hangers.

3. Suspend the BASE-CF with a repeated interval of 600 mm, measured from the centrums of the profiles (cc).
4. Measured along the length of the BASE-CF, the connection to the ceiling must be made every 600 mm.

5. Level the height of the subconstruction using a laser and secure with the locking pin.

6. Secure the position of the NONIUS-CD by bending the 2 wings.

7. When needed, connect the BASE-CF in-line with profile 3263 and assure the cc distance between the fixation positions remains constant.

8. Snap the distance profile 3262 perpendicular to the BASE-CF every 1200 mm.

9. Two distance profiles Capax 3262 will partially run parallel, where mounted on the same BASE-CF.

10. Optionally, install Acoustex-9 insulation onto the “T” section of the BASE-CF. The width of the Acoustex-9 will be 544 mm.

11. Attach the ribs to the BASE-CF.
The end of a Feltfon rib must not protrude unsupported more than max 200 mm.

12. The in-line connection of 2 ribs should be secured by a BASE-CF profile.
