Shear banded couplings are a requirement of the UK water companies when connecting onto their assets. This requirement forms part of Water Industry Specification (WIS) 4-41-01, which outlines the requirements to connect pipes on adopted systems using only shear banded couplings. The shear band gives the connection added protection against shear loads that could cause the pipes to become mis-aligned.

Manufactured using galvanised steel, this manhole cover by Clark-Drain creates a robust cover with a load rating of 10 tonnes. Ideal for use in driveways and restricted access areas, the manhole is internally sealed to prevent odours leaking and the cover can be rotated to fit with the design of the surface finish for convenience.
