Side-to-side attachment in a curved wall
EC Series Headers and panels can also be attached
horizontally to form a curved wall using the optional EC
Series Curving Kit (P/N 90354270).
• EC-10 panels can be installed in a concave curve with
panels angled at up to 15° to each other.
• EC-20 panels can be installed in a concave or convex
curve with panels angled at up to 20° to each other.
To install panels in a curved configuration:
1. See Figure 15. Unscrew the 2.5 mm Allen bolts
shown and remove the straight side-to-side
alignment cones B and washers A close to the top
and to the bottom of one side of each panel. Store all
components for possible re-use.
2. Remove the similar alignment cones from the
Headers.
3. Suspend the panels vertically as described earlier.
4. See Figure 16. Install the thumbwheels A supplied in the Kit on the top and bottom profiles of each
panel, using the supplied locknuts to secure them in place so that they will not drop out of the panel if
loosened too much.
5. Insert two curved plates (or 'bananas')
B supplied in the Kit in their slots on the
top and bottom profiles. Once the
correct angle is obtained, lock the
columns by tightening thumbwheels A.
6. Install curving plates using the same
method in the slots in the bottom profile
of the Headers.
7. When the installation is disassembled,
the thumbwheels A can be tightened
and left in position but remove the
'bananas' B and store them safely in the
flightcase for possible re-use.
8. Reinstall the alignment cones (see
Figure 14) on the sides of panels and
Headers before installing panels in a flat
wall.
