The MetacaulkÂ® Cast-In-Place firestop device can save the cost of drilling holes in each floor of a building after the concrete floors are poured by providing an array of firestopped pass-through sleeve systems. Designed for use by mechanical, electrical, and plumbing contractors, this highly intumescent device can be attached to either the plywood form or directly to a metal deck prior to the concrete floor being poured. Once the concrete is poured and the forms are removed, the devices provide a firestopped opening that allows for plastic, metal, insulated pipes, line sets, and cable or wire bundles to pass through it. The larger-than-normal opening in the top of the sleeve allows for flexible positioning of the penetrating item. Guides in the sleeve automatically position the penetrating item through the hole in the device.
