Each internal pole has red warning bands alerting you to the approaching
end of the extension. Once the red band comes into view to insure a stable
connection and avoid damage to the wands collapse the wand until the red
band disappears and lock the wand in place. This captured length protects
the stability of the wand system at height and prevent damage to the wand
from unsupported leverage when working against the surface being cleaned.
The top pole has a chrome metal locking adaptor to attach the desired wand
on the end.
