This Amendment No. 20 to Schedule 13D on the Common
Stock of Nortek, Inc. (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 October 26, 1988.
Unless otherwise indicated, all capitalized terms used herein but
not defined herein shall have the same meaning as set forth in
the Schedule 13D. This Amendment is being filed to correct an
arithmetical error in Item 5 (a) of Amendment No. 19.
Item 5. Interest In Securities Of The Issuer
Item 5 to Schedule 13D is amended, in pertinent part, as
follows:
(a) The aggregate number and percentage of Securities
to which this Schedule 13D relates is 1,458,565 shares, repre-
senting 15.20% of the 9,593,979 shares outstanding. This latter
number of shares is arrived at by adding the number of shares of
Common Stock reported as being outstanding in the Issuer's most
recently filed Form 10-Q for the quarter ended March 29, 1997
(9,102,133) to the number of shares of Special Common Stock
reported as being outstanding therein (491,846). The Reporting
