POLYCAST® 900 Series

Installation Chair
Installation chairs are the most efficient and economical means of setting up a precast trench system. The installation chair supports the ends of the channel, aligns and locks the joints rigidly together, and prevents the channels from floating. Adjusting channel elevation is easy. One chair is required for every joint. The chair is made from 1018 hot-rolled steel and has a zinc-plated finish

Pipe Adapter End Caps
POLYCAST® end caps are used to enclose or provide piping transitions to outlet or inlet ends of the channel whenever catch basins are not being used. End caps output to a 4″ pipe. The material is ABS plastic.
Polymer concrete end caps are also available.
