Manhole Shutters

Pre-formed steel shutters for forming concrete surrounds to manholes.
• Each manhole shutter is made up of a combination of the modular panel
components listed in the table below (A, B & C)
• Two panel heights of 900mm and 1800mm
• Three panel sizes combine for manhole ring diameters from 675mm to 2700mm
• Rapid assembly using simple pin and wedge systems
