The Mini roll door is
for internal use only.
The Mini roll door
structure is manufactured
from a combination of
galvanised sheet steel and
aluminium extrusions
which are powder coated
in a range of standard
colours.
The 80mm wide
guide ensure this door is
unobtrusive when installed
in office or commercial
environments.
The door structure is self
supporting but requires
fixing to the floor via it’s
foot brackets and at high
level for security and
rigidity.

The bottom of the canvas
curtain is reinforced with a
horizontal steel tube and
the curtain has small
bearing wheels at
horizontal centres that
operate along and inside
the guides to ensure the
curtain is kept taught.

Electrical specifications
and activation systems
All door types are
supplied with a geared
motor designed for
intensive use. The
motor is connected to
the shaft by a flexible
coupling to absorb any
vibrations produced,
thus increasing the
operator’s life span.
The motor incorporates
factory set limit switches,
an electric brake and
emergency brake
release.
The door can be opened
and closed in the event of
power failure by hand
crank. A safety interlock
micro switch ensures that
the door cannot be
operated electrically unless
the hand crank has been
replaced.
