Metal Strip - Standard Sizes
|
|
|
|
|
|
The size and shape of the metal
channel determines, for the most
part, brush size and density. The
primary function of the channel is
to hold the fill material, however,
the channel itself can be used as a
mounting surface or designed to fit
into shaped holders.
The standard channel shape is 'flat
back' as shown. Other shapes are
possible with special tooling.
Although different manufacturers may
use the same size letter and number
for a strip brush, there may be
significant differences in the
actual dimensions after forming.
Thus if the strip brush is to be
inserted into an extrusion, holder,
bracket assembly or mating part it
should be submitted and retained by
Felton to be used as an additional
gauge to insure proper fit.
