IMPORTANT:

The

installation should be the border panel size from the wall.

In a 2' x 2' panel installation, the

ﬁ

rst main beam can be the

border panel size or the border panel + 24" from the wall.

EXAMPLE

:

See Sample Room Han

g

er Layout – 2' 6" from the

wall for a 2' x 4' panel. QuickHang brackets should not be

spaced more than 4' apart in any direction
