The STI KIT-316 is a louver kit that adds ventilation to STI Stopper II and Weather Stopper installations. Specifically, the louvers install on the STI-3100 2-inch conduit spacer. As a result, protected pull stations get extra airflow in enclosed or weather-exposed mountings.
What the STI KIT-316 is for
Weather Stopper covers seal a pull station against rain and dust using closed-cell gaskets. However, some installations need airflow behind the cover. Therefore, STI offers this louver kit for the STI-3100 spacer used with larger or surface-mounted pull stations.
