Specified Technologies SBR25 SpecSeal Firestop Block, 2" x 5" x 8", Brick Red

Protect critical cable and conduit penetrations with the Specified Technologies SpecSeal Firestop Block—designed for fast, reliable firestopping in security, surveillance and IT environments. This penetration firestop block is made from intumescent urethane foam that expands under heat to form a tight, smoke‑resistant seal around cables, conduits and innerducts. At a practical 2" x 5" x 8" size (brick red), the SBR25 compresses and stacks like a foam brick for simple installs and can be trimmed on-site to fit irregular openings.

Ideal for server rooms, monitoring centers and camera infrastructure, the SpecSeal block is reinstallable to accommodate cable additions and changes, reducing downtime during upgrades to security or network systems. Lightweight and fiber‑free, it delivers superior air leakage ratings and supports common two‑hour firestop requirements without special tools or cure time. With a maximum operating temperature of 130°F and packaged for jobsite efficiency, this block streamlines firestop compliance for electricians, low‑voltage contractors and facility managers.
