Wiremold FlameStopper Fittings protect the integrity of a firewall, without adding caulk or putty after cables are installed. Now redesigned for both new installations and retrofits, FlameStopper fittings combine a built-in-fire-stopping intumescent material with an enclosed thru-wall penetration. FlameStopper thru-wall fittings are easy to install and inspect. Best of all, they’re the proven way to stop fire in its tracks.
