SpecSeal® SSP Firestop Putty is a high‑performance, non‑hardening intumescent firestop putty designed to seal cable penetrations and electrical outlet boxes with ease. Its soft, moldable formulation allows installers to quickly hand‑form the putty around grouped cable bundles, creating a re‑enterable firestop seal that supports future cable moves, adds, or changes without material waste. When applied to outlet boxes, SpecSeal SSP Putty works smoothly into voids, gaps, and seams, forming a continuous, code‑compliant barrier that helps prevent the spread of fire, smoke, and products of combustion. Ideal for commercial, industrial, and low‑voltage applications, SSP Putty offers reliable firestopping performance, excellent adhesion, and long‑term flexibility across a wide variety of substrates.
