Lightweight Roller Shutter

     SWIVEL BELT WINDER - for shutters up to 15kg

     This type of operation is used when the roller shutter is fitted on
     the outside of the property and is lowered/raised using the
     Swivel Belt Winder from the inside.   The grey belt is pulled up
     and down to lower and raise the shutter.  The swivel winder 
     coils the belt when it is pulled to open the shutter.  The belt is
     14mm wide and grey in colour and a guide tube to protect the
                              belt through the building wall.  The shutter locks by using the
                              locking spring which connects the curtain to the barrel
                              and lock out in the back of the shutter box.

      GEARED BELT WINDER - for shutters between 15kg and 25kg

      This is the same as the Swivel Belt Winder but uses a crank
      handle to raise and lower the shutter.  The Geared Winder
      works at 1:3 ratio with removable handle. The shutter locks by 
      using the locking spring which connect the curtain to the barrel and
      lock out in the back of the shutter box.

      ROD CRANK OPERATION - for shutters up to 25kg

      This type of operation is usually on windows where the shutter
      is external and is operated internally using a geared rod crank
      handle which hangs vertically and secures into a clip when
      not in use. The shutter is lowered and raised by turning the
      handle in a clockwise or anti clockwise direction.  The shutter 
      locks by using the locking spring which connect the curtain to
                              the barrel and lock out in the back of the shutter box.

     SPRING LOADED

      Roller Shutters usually installed mainly over doorways or
      Serveries are raised up and down by lifting and lowering the
      curtain by hand.  The roller shutter has a spring in the barrel
      which helps lifting the shutter.  As standard a central bottom
      lath lock is provided which has a key in the bottom lath and
      bolts shoot into the guides rails at each side.  The Bottom
                          lath lock can be operated from both sides but has a secure
                              and non-secure side to the lock.  Optional bullet locks are
                              available which are pins that go through the guide rails each side.

      ELECTRIC  - (N.B. minimum shutter width 750mm) 

      Electric shutters are usually fitted on larger openings where
      Manual Operation is not suitable or where the operator
      requires an easy, clean and user friendly type of operation.  
      Single phase tubular motors are enclosed within the barrel
      giving full protection from the elements.  Electric Roller
      Shutters can be controlled individually or grouped to one
                              controller.  The controllers available include internal rocker
                              switch, security key switch or Remote Control.  Manual
                              overrides are available on Electric Roller Shutters which
                              allow the shutter to be operated when the power to the
                              shutter has failed.
