STI CD600DK Deck Adapter 6 in H 6 in D Red

STI CD600DK Deck Adapter for CD600

The STI CD600DK is a red plastic deck adapter designed for use with the CD600 model. It provides a 6 inch height and 6 inch diameter connection point for facility and traffic safety installations. The adapter carries a 3 hour fire rating and meets UL Classified, FM Approved, FBC System Compatible, and ASTM E814 (ANSI/UL1479) standards. It suits contractors needing a listed penetration component.

Fire-rated penetration seal limits

This adapter functions as a firestop component within tested assemblies rated for three hours. Its listing under ASTM E814 (ANSI/UL1479) confirms performance for through-penetration fire stops. The UL Classified and FM Approved marks indicate compliance with those specific test standards. It does not serve as a structural support or load-bearing element in the assembly.

6 inch diameter plastic body specification

The critical specification is the 6 inch diameter plastic body matched to the CD600 series. This exact diameter ensures the adapter fits the intended penetration opening and maintains the tested fire rating. Using an adapter with a different diameter voids the UL and FM listings. Buyers must verify the penetration size matches this 6 inch dimension before purchase.
