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
