The shutter curtain is constructed from interlocking galvanised steel laths and a heavier duty manufactured bottom rail, running in steel side channels, mounted on mild steel support angles which are bolted to the structure. The curtain weight is supported from a suitable steel tube barrel assembly at high level, running on steel bearings. The barrel assembly is supported between mild steel endplates in a flag guide arrangement and driven through gears. A galvanised steel coil casing and flame trap fascia are provided as standard.
Manual operation by means of continuous galvanised haul chain for opening and a pull cord disengage device to give controlled descent on closing. Due to the gearing within the controlled descent operator, the manual operation is a slow process and is designed for occasional use only.
