Swivel belt / geard belt shutters are raised and lowered from inside by a belt. Depending upon shutter size the belt is operated manually or by geared crank handle. This is a lower security option.
Rod crank Shutters are raised and lowered from inside by a geared rod crank winding handle which hangs down vertically underneath the box and secures on a clip when not in use.
Spring loaded for external operation on exit doors, shutters can be spring loaded with a transverse key lock in the bottom slat. Also a popular option for bar, servery, counter, cabinet and kiosk applications. (N.B. The bottom slat projects below the shutter when fully raised, check that this will not obstruct outward opening doors).
Electric Motors are required on larger shutters and are optional on smaller shutters. Tubular motor fit inside the axle and require a 3 amp fuse. Operation is by rocker switch, key switch or remote control. A manual override can be specified to operate from inside. Where desirable a manual override can also be engaged through the outside of an externally fitted shutter box. Under these circumstances a lockable override cover is available as an optional extra to maximise security. Multi-shutter electric installations can be wired to operate from a central or group switches.
