These RectorSeal Metacaulk firestop putty pads are essential for maintaining fire safety in buildings! The 7x7 inch pads are designed to protect metal electrical cabinets, outlet boxes, and mechanical cabinets by maintaining the fire rating of walls when there are penetrations. They're rated for up to 3 hours of fire protection according to ASTM E 814, UL 1479, and ULC/CAN4-S115-M standards - that's serious protection. The amazing thing is you only need one 1/8-inch thick pad to achieve a 1-2 hour fire rating - no multiple layers required. They also provide excellent soundproofing with an STC rating of 60, reducing noise transmission between rooms. Installation is super easy - just mold by hand with no curing time, mixing, or special skills needed. The material expands when exposed to fire, creating an even better seal during emergency situations. There are no asbestos fillers, so they're safe to handle, and you don't need additional putty for conduit connections. These are must-have materials for electricians, contractors, and building professionals who need to maintain fire code compliance while installing electrical systems. Whether you're working on commercial buildings, multi-family housing, or any structure where fire separation matters, these putty pads deliver reliable, code-compliant protection that's both effective and easy to install properly.
