FS400 SpecSeal 4" Ready Sleeve

The FS400 4-Inch Firestop Ready Sleeve Kit is a complete cable penetration solution designed for new installations requiring a durable, organized, and fire-protected cable pathway. Featuring a preformed steel sleeve, steel escutcheon plates, intumescent gaskets, and firestop putty, this kit simplifies the installation of cable penetrations through compatible fire-rated wall assemblies.

Engineered for professional electrical and telecommunications installations, the FS400 features a 4-inch steel cable sleeve with smooth rolled edges. This design eliminates the need for separate protective bushings while helping prevent damage to cables during installation.

The included steel escutcheon plates and intumescent gaskets provide a coordinated mounting and sealing arrangement. These components are designed to replace traditional steel strut and strap supports in approved installations, reducing the number of separate materials required.

The kit also includes intumescent firestop gaskets and SSP firestop putty to help maintain the fire-resistance integrity of compatible penetrated wall assemblies. When installed according to an approved firestop system, these materials help restrict the spread of fire and smoke.

Designed for wall assemblies up to 10 inches thick, the FS400 accommodates a variety of commercial construction requirements. Its 4-inch nominal sleeve size provides a larger cable pathway for installations involving multiple communication, networking, security, or low-voltage cables.

The ready-to-install configuration helps reduce installation time by combining the principal sleeve, mounting, sealing, and identification components in one package. Wall identification labels are included to support proper identification and inspection of completed penetrations.

For installations involving larger wall openings, compatible oversized escutcheon plates and gaskets are available separately.

Ideal for new construction, structured cabling installations, data centers, telecommunications infrastructure, and commercial building projects, the FS400 provides a practical solution for creating organized, protected cable pathways.
