The four framework types detialed below range from light to heavy duty. The 'Superflex', 'Multiflex' and 'Interflex' Frames house a vertical spring unit mechanisum in the top of each door tube. The 'Powerflex' frame houses a unit in both the top and bottom of each tube. The mechanism is a double action, adjustable tension, torsion spring unit concealed in the door frame and is virtually maintenance free.

• Superflex - Manufactured from high quality extruded aluminium section, that has smooth lines and no projections. Used frequently within the food industry this is a lighter duty door than others in the range and has the panel fixings concealed within the framework. Suitable for use on internal openings with pedestrian, hand or light powered traffice on openings up to 2400mm wide by 2438mm high.
  
  
• Multiflex - Manufactured from 43mm o/d heavy wall mild steel steam tube, with horizontal gusset plate and vertical mild steel flats to hold the panel in position.

Flexible doors of all specifications can be operated automatically if desired. They often are used when an optimum flow of traffic is required, for example in a busy warehouse or production area.
Flexible doors are modified for automatic operation in one direction. The direction must be specified prior to order but the doors are able to swing both ways manually also. Flexible doors can be automated either pneumatically (air) or electrically.

• Pneumatic (Air) Operation - Pneumatic operation requires an 80psu air supply and a single phase 240V power supply terminated within a fused isolator approximately one metre from the opening.
  A feature of having pneumatic flexible doors is that each leaf has a separate cylinder so that opening and closing cycles can be regulated independantly, whereas, with the electric system there is one motor that drives both leaves through a constant speed reduction gear which cannot be varied.
  
  
• Electric Operation - Electric operation requires a 440v, 3 phase neutral & earthed power supply terminated within a fused isolator approximately one metre from the opening. In the event of a power failure the doors can still be used as conventional 'crash' doors as they are driven through the vertical spring unit mechanisum at the top of the door tube. 

Both systems are supplied complete with a control panel which incorporates an adjustable timed return facility that enables the doors to close automatically once the desired stand open time has elapsed.

• Pull switches.
• Push buttons.
• Photocell Beam and Reflector.
• Microwave Radar Scanner Detection Units.
• Induction loops.
