Manhole Shutters

About Manhole Shutters

Manhole Shutters are designed to support a nominal concrete surround of 150mm to the outside of standard precast manhole rings. Three modular panels widths (A, B and C) enable a range of diameters to be accommodated up to a maximum internal precast ring diameter of 3.0m. The panels are joined together using a simple pin and wedge assembly system.

  • Available in steel
  • Panel height of 1800mm
  • Three panel widths will configure shuttering for most pre-cast manhole rings
  • Nominal concrete surround of 150mm (see table)
  • Rapid and re-usable. No special tools required
  • Pre-curved steel construction
