Trelleborg 172 Load distributor, Integrated Sealing System for Sewer and Stormwater Pipes

System description

Trelleborg 172 Load distributor is designed for manhole systems in accordance with DIN V 4034-1. It is a load distribution element that is placed on the outer spigot end face of the manhole components in addition to the sealing ring. The plastomeric strip compensates for any unevenness between the load bearing surfaces of the manhole components, distributing the vertical load and preventing concrete to concrete contact which could lead to point loading and structural failure.
