Press Release

NEW YORK, May 20, 2011 (BUSINESS WIRE) --

Griffon Corporation (NYSE: GFF) announced today that it will consolidate the leadership of its Home & Building Products segment with both Ames True Temper ("ATT") and Clopay Building Products ("CBP") reporting to Eugene (Gene) C. Colleran as the new President of Home & Building Products and CEO of ATT. Duane R. Greenly, CEO of ATT, is retiring after nine years with ATT, the last three as CEO. Griffon believes that this unified management structure will provide significant operating and financial benefits.

Ron Kramer, Griffon's CEO, said "During Duane Greenly's tenure, ATT has grown to be a true market leader in the lawn and garden tool industry. We thank Duane for his years of service and strong business leadership."

Mr. Colleran has had responsibility for CBP for the last eleven years. Prior to joining Clopay, Mr. Colleran spent nine years with Newell Company (NYSE: NWL), most recently as President of BernzOmatic, the world's largest manufacturer of gas powered hand torches. Prior to Newell, he spent nine years in various sales and marketing management roles with Chicago based United States Gypsum (NYSE: USG).

Mr. Kramer concluded, "We expect Gene Colleran will continue to grow and develop our Home & Building Products business. With pro forma March 31, 2011 TTM revenue of over $845 million and adjusted TTM EBITDA in excess of $80 million, we have significant opportunities to expand the business and improve our profitability as the housing markets ultimately recover."
