Item 1.                                Security and Issuer
This Amendment No. 7 to Schedule 13D on the Common Stock of Griffon Corporation (the “Issuer”) is being filed on behalf of the undersigned to amend the Schedule 13D, as amended (the “Schedule 13D”), which was originally filed on February 19, 2008.  Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meaning as set forth in the Schedule 13D.

Item 2.                                Identity and Background
Item 2 to Schedule 13D is amended, in pertinent part, as follows:
This statement is being filed by Mario J. Gabelli (“Mario Gabelli”) and various entities which he
directly or indirectly controls or for which he acts as chief investment officer.  These entities engage in various aspects of the securities business, primarily as investment adviser to various institutional and individual clients, including registered investment companies and pension plans, and as general partner of various private investment partnerships.  Certain of these entities may also make investments for their own accounts.
The foregoing persons in the aggregate often own beneficially more than 5% of a class of a particular issuer.  Although several of the foregoing persons are treated as institutional investors for purposes of reporting their beneficial ownership on the short-form Schedule 13G, the holdings of those who do not qualify as institutional investors may exceed the 1% threshold presented for filing on Schedule 13G or implementation of their investment philosophy may from time to time require action which could be viewed as not completely passive.  In order to avoid any question as to whether their beneficial ownership is being reported on the proper form and in order to provide greater investment flexibility and administrative uniformity, these persons have decided to file their beneficial ownership reports on the more detailed Schedule 13D form rather than on the short-form Schedule 13G and thereby to provide more expansive disclosure than may be necessary.
(a), (b) and (c) - This statement is being filed by one or more of the following persons: GGCP, Inc.  (“GGCP”), GAMCO Investors, Inc. (“GBL”), Gabelli Funds, LLC (“Gabelli Funds”), GAMCO Asset Management Inc. (“GAMCO”), Teton Advisors, Inc. (“Teton Advisors”), Gabelli Securities, Inc. (“GSI”), Gabelli & Company, Inc. (“Gabelli & Company”), MJG Associates, Inc. (“MJG Associates”), Gabelli Foundation, Inc. (“Foundation”),  and Mario Gabelli.  Those of the foregoing persons signing this Schedule 13D are hereafter referred to as the “Reporting Persons”.
GGCP makes investments for its own account and is the controlling shareholder of GBL.  GBL, a public company listed on the New York Stock Exchange, is the parent company for a variety of companies engaged in the securities business, including those named below.
GAMCO, a wholly-owned subsidiary of GBL, is an investment adviser registered under the Investment Advisers Act of 1940, as amended (“Advisers Act”).  GAMCO is an investment manager providing discretionary managed account services for employee benefit plans, private investors, endowments, foundations and others.
GSI, a majority-owned subsidiary of GBL, is an investment adviser registered under the Advisers Act and serves as a general partner or investment manager to limited partnerships and offshore investment companies.  As a part of its business, GSI may purchase or sell securities for its own account.  It is the immediate parent of Gabelli & Company. GSI is the general partner or investment manager of a number of funds or partnerships, including Gabelli Associates Fund, Gabelli Associates Fund II, Gabelli Associates Limited, ALCE Partners, L.P., and Gabelli Multimedia Partners, L.P.  GSI and Marc Gabelli own 45% and 55%, respectively, of Gabelli Securities International Limited (“GSIL”). GSIL provides investment advisory services to offshore funds and accounts.   GSIL is an investment advisor of Gabelli International Gold Fund Limited, Gabelli European Partners, Ltd., and Gabelli Global Partners, Ltd.
Gabelli & Company, a wholly-owned subsidiary of GSI, is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (“1934 Act”), which as a part of its business regularly purchases and sells securities for its own account.

GBL is the largest shareholder of Teton Advisors, an investment adviser registered under the Advisers Act, which provides discretionary advisory services to The GAMCO Westwood Mighty Mites sm  Fund, The GAMCO Westwood Income Fund , The GAMCO Westwood Small Cap Fund and B.B. Micro-Cap Growth Fund.

Investment Manager of the Foundation. Elisa M. Wilson is the President of the Foundation.

For information required by instruction C to Schedule 13D with respect to the executive officers and directors of the foregoing entities and other related persons (collectively, “Covered Persons”), reference is made to Schedule I annexed hereto and incorporated herein by reference.
(e) - On April 24, 2008, Gabelli Funds  settled an administrative proceeding with the Securities and Exchange Commission (“Commission”) regarding frequent trading in shares of a mutual fund it advises, without admitting or denying the findings or allegations of the Commission.  The inquiry involved Gabelli Funds’ treatment of one investor who had engaged in frequent trading in one fund (the prospectus of which did not at that time impose limits on frequent trading), and who had subsequently made an investment in a hedge fund managed by an affiliate of Gabelli Funds.  The investor was banned from the fund in August 2002, only after certain other investors were banned.  The principal terms of the settlement include an administrative cease and desist order from violating Section 206(2) of the Investment Advisers Act of 1940, Section 17(d) of the Investment Company Act of 1940 (“Company Act”), and Rule 17d-1 thereunder, and Section 12(d)(1)(B)(1) of the Company Act, and the payment of $11 million in disgorgement and prejudgment interest and $5 million in a civil monetary penalty.  Gabelli Funds was also required to retain an independent distribution consultant to develop a plan and oversee distribution to shareholders of the monies paid to the Commission, and to make certain other undertakings.
               In September 2008, Gabelli Funds reached agreement in principle with the staff of the Commission, subject to Commission approval, on a previously disclosed matter that had been ongoing for several years involving compliance with Section 19(a) of the Investment Company Act of 1940 and Rule 19a-1 thereunder by two closed-end funds.  The agreement was finalized with the Commission on January 12, 2009.  The provisions of Section 19(a) and Rule 19a-1 require registered investment companies, when making a distribution in the nature of a dividend from sources other than net investment income, to contemporaneously provide written statements to shareholders that adequately disclose the source or sources of such distribution.  While the two funds sent annual statements and provided other materials containing this information, the shareholders did not receive the notices required by Rule 19a-1 with any of the distributions that were made for 2002 and 2003.  Gabelli Funds believes that the funds have been in compliance with Section 19(a) and Rule 19a-1 since the beginning of 2004.  As part of the settlement, in which Gabelli Funds neither admits nor denies the findings by the Commission, Gabelli Funds agreed to pay a civil monetary penalty of $450,000 and to cease and desist from causing violations of Section 19(a) and Rule 19a-1.  In connection with the settlement, the Commission noted the remedial actions previously undertaken by Gabelli Funds.
                      (f) - Reference is made to Schedule I hereto.

Item 5 to Schedule 13D is amended, in pertinent part, as follows:
(a) The aggregate number of Securities to which this Schedule 13D relates is 3,934,280 shares, representing 6.64% of the approximately 59,275,870 shares outstanding as reported by the Issuer in its Form 10-Q for the quarterly period ended December 31, 2008.
