The Nelson Firestop MPS Multi-Plug System by Emerson is cable and pipe sealing solution for use in commercial building, wall and floor penetrations, as well as in marine bulkhead and deck applications, offshore platforms, and power stations. To bring a structure back up to its original fire rating after a hole is cut into it, the system creates an airtight seal at the opening, preventing passage of fire, water, gas, sound and blast pressures by using Tecron rubber modules that fit snuggly around the pass-through pipes and cables. According to the company, this helps extend the time needed to safely evacuate a building or maritime vessel in the event of a fire, while also limiting property loss and water damage. Unlike caulk and mortar, each time a contractor adds or removes a cable within the MPS Multi-Plug System, they do not need to remove and replace the materials. Instead, an MPS block is taken out and re-installed with the new cable placed inside it. MPS Plugs are available in 2-in. to 8-in. pipe sizes, and each different cable diameter requires a specific size module.
