While working in the commercial tenant finish-out industry, Chuck Longhenry realized there had to be a faster and less intrusive way to seal the core and penetration holes that typically contain electrical and data wires in multi-story buildings. After two years of trial and error he perfected and applied for a patent on the SealCore Safety Plate, an innovative way to seal core holes during construction and post-construction that saves money and reduces installation time while meeting all building codes.

Sealing core holes using the traditional method can take an hour per hole, with a worker having to go to the floor below, remove the ceiling, put a steel or fire-rated plywood plate on the underside of the hole, go to the floor above, mix concrete, fill the hole, and clean up.
With SealCore Safety Plate the same job takes as little as 35 seconds.
The SealCore Safety Plate is inserted into the hole, lifted, tightened with an Allen wrench, and filled with fire-rated foam. A real-time video showing how quickly and easily the SealCore Safety Plate can be installed may be seen at www.LongHenryIndustries.com.
The SealCore Safety Plate is made of high grade plate steel and comes with everything needed to install it: the SealCore component, Allen wrench, fire-rated foam, and instructions. No additional tools are needed, no experience is required, and it meets the International Building Code Four-Hour Fire Rating.
SealCore Safety Plate can be used with slabs between 3” and 12” thick and is available in sizes that fit holes ranging from 3” to 5-3/4” in diameter. They’re manufactured in the United States using local workers for Longhenry Industries of Aubrey, Texas.
