• Allows for fast, easy cast-in firestop installation on fluted metal decks
• Designed for use with 3M™ Fire Barrier Cast-In Devices
• Easy snap-in assembly of Cast-In Devices saves time and requires no fasteners
• One-piece body attaches easily to metal decking before slabs are poured
• Used in conjunction with Fire Barrier Cast-In Devices, adaptors are firestop tested for up to 3-hours in accordance with ASTM E 814 (UL 1479)

3M™ Fire Barrier Cast-In Device Metal Deck Adaptors are one-piece plastic body adaptors for one-step firestopping on fluted metal decks. Installers simply snap a metallic or non-metallic 3M™ Fire Barrier Cast-In Device into the adaptor – no fasteners are required – and attach it to the metal decking before concrete slabs are poured. Adaptor/device assemblies are firestop tested up to 3 hours.

Simply a Better Way to Firestop
To expand the versatility of our time- and money-saving cast-in firestopping, our 3M™ Fire Barrier Cast-In Device Metal Deck Adaptors let technicians install our 3M™ Fire Barrier Cast-In Devices onto uneven metal fluted decking before concrete slabs are poured. This one-piece plastic adaptor features snap-in attachment to the Fire Barrier Cast-In Device – no tools or fasteners are required. It installs quickly and easily onto fluted steel pan decks for drain, waste and vented or closed pipe systems. The adaptor accepts Cast-In Devices for both plastic and metal pipes.

Recommended Applications

• Use in conjunction with metallic and non-metallic 3M™ Fire Barrier Cast-In Devices
