This is a genuine Certikin HD102 parallel extension throat for liner pools.
The Certikin HD102 is suitable for extending the parallel tunnel on a stadard Certikin HD100 Skimmer in concrete pools.
Certikin Parallel Extension Throats are used to improve flow, providing an effective funnel through to the skimmer. This additional part is easy to slide on to the end of the skimmer.
It is used for extending the throat of the skimmer for pools with thicker walls i.e. double skinned block construction or concrete, or installations where a deck mount cover requires the skimmer body to be further away from the pool body.
Incorporates a front bezel eliminating the need for expensive finishing work. The Certikin Skimmer Max Flow Rate is 4.5m3 per hour at 0.3m/s.
This is for liner pools and includes liner faceplates and gaskets.
