RectorSeal Metacaulk® Fire-Rated Putty Pads – 6" × 7"

Protect electrical outlet boxes without compromising the fire rating of your walls. RectorSeal Metacaulk® Fire-Rated Putty Pads are a fast, reliable firestop solution designed to restore the fire resistance of electrical boxes installed in fire-rated gypsum wall assemblies. Their moldable, non-hardening intumescent formula expands when exposed to high temperatures, helping prevent the spread of fire, smoke, and hot gases through electrical penetrations.

Ready to install with no tools or mixing required, these flexible putty pads conform easily around electrical boxes, conduit, switches, and receptacles, creating an effective firestop seal in minutes. Their non-curing composition remains pliable over time, making future modifications or maintenance simple while maintaining dependable fire protection.

Ideal for commercial buildings, hospitals, schools, multifamily housing, and industrial projects, Metacaulk® Fire-Rated Putty Pads help contractors meet fire code requirements while reducing installation time and improving jobsite efficiency.
