Metacaulk Putty Sticks

Metacaulk Putty Sticks Firestop Putty for Electrical and Penetration Firestop Systems Metacaulk Putty Sticks are moldable, non-curing, one-component fire-rated materials designed for through-penetration firestop systems. When exposed to fire, the putty intumesces, forming an insulating char that prevents the spread of flames, smoke, gas, and water through penetration openings. This product is ideal for use by electrical distributors and switchgear suppliers requiring reliable firestop solutions for wire and cable penetrations, conduit, and electrical boxes.
