Exhibit 99.3

FORM OF LETTER TO NOMINEE HOLDERS
WHOSE CLIENTS ARE BENEFICIAL HOLDERS

BLUELINX HOLDINGS INC.

[•] Shares of Common Stock
Offered Pursuant to Rights Distributed to Record Stockholders of
BlueLinx Holdings Inc.

[•], 2011

To Securities Dealers, Commercial Banks,
Trust Companies and Other Nominees:

     This letter is being distributed to securities dealers, commercial banks, trust companies and other nominees in connection with the rights offering (the “Rights Offering”) by BlueLinx Holdings Inc. (the “Company”) of shares of its Common Stock, par value $0.01 per share (the “Common Stock”), pursuant to transferable subscription rights (the “Rights”) distributed to all holders of record (“Record Holders”) of shares of Common Stock, at the close of business on [•], 2011 (the “Record Date”). The Rights are described in the Company’s Prospectus, dated [•], 2011 (the “Prospectus”).

     In the Rights Offering, the Company is offering an aggregate of [•] shares of its Common Stock pursuant to the Prospectus. The Rights will expire, if not exercised, by 5:00 p.m., Eastern Time, on [•], 2011, unless extended by the Board of Directors of the Company, provided that the expiration date of the Rights Offering may not be extended by more than [•] days without the prior written consent of Cerberus ABP Investor LLC (“Cerberus”) (as it may be extended, the “Expiration Date”).

     As described in the accompanying Prospectus, each Record Holder will receive one Right for every share of Common Stock owned of record as of the close of business on the Record Date.

     Each Right allows the holder thereof to subscribe for [•] of a share of Common Stock (the “Basic Subscription Right”) at the cash price of $[•] per whole share (the “Subscription Price”). Fractional shares or cash in lieu of fractional shares will not be issued in the Rights Offering. Fractional shares will be rounded down to the nearest whole number. As an example, if you owned 1,000 shares of Common Stock as of the Record Date, you would receive 1,000 subscription rights pursuant to your Basic Subscription Right that would entitle you to purchase [•] shares of common stock ([•] rounded down to the nearest whole share) at a subscription price of $[•] per whole share.

     In addition, each holder of Rights (other than Cerberus) who exercises his Basic Subscription Right in full will be eligible to subscribe (the “Over- Subscription Privilege”), at the same Subscription Price of $[•] per whole share, for additional shares of Common Stock if any Underlying Shares are not purchased by other holders of Rights under their Basic Subscription Rights as of the Expiration Date (the “Excess Shares”). Each holder of Rights may exercise his Over-Subscription Privilege only if he exercised his Basic Subscription Right in full and other holders of Rights do not exercise their Basic Subscription Rights in full. If there is not a sufficient number of Excess Shares to satisfy all requests for subscriptions made under the Over-Subscription Privilege, the Company will allocate the remaining Excess Shares pro rata, after eliminating all fractional shares, among those Rights holders who exercised their Over-Subscription Privileges in proportion to the number of shares of Common Stock owned by such Right holder on the Record Date, relative to the number of shares of Common Stock owned on the Record Date by all Right holders exercising their Over-Subscription Privilege. If this pro rata allocation results in any person receiving a greater number of Excess Shares than the person subscribed for pursuant to the exercise of the Over-Subscription Privilege, then such person will be allocated only that number of Excess Shares for which the person over-subscribed, and the remaining Excess Shares will be re-allocated among all other persons exercising the Over-Subscription Privilege on the same pro rata basis described above. The proration process will be repeated until all Excess Shares have been allocated. For the purposes of determining their eligibility for the Over-Subscription Privilege, holders will be deemed to have exercised their Rights under the Basic Subscription Right in full if they subscribe for the maximum number of whole Underlying Shares available under their Basic Subscription Right. See “The Rights Offering—The Subscription Rights” in the Prospectus.

     The Company has entered into an investment agreement with Cerberus, who beneficially owns approximately 55% of the outstanding Common Stock prior to giving effect to the Rights Offering, under which, subject to the terms and conditions thereof, Cerberus has agreed to purchase from us, at the Subscription Price, unsubscribed shares of Common Stock such that gross proceeds of the Rights Offering will be no less than $60.0 million.

     The Rights are evidenced by a Rights certificate (a “Subscription Rights Certificate”) registered in your name or the name of your nominee. Each beneficial owner of shares of Common Stock registered in your name or the name of your nominee is entitled to one Right for every share of Common Stock owned by such beneficial owner as of the Record Date. The Rights will be transferable until 4:00 p.m., New York time, on the last trading day preceding the Expiration Date, at which time they will cease to have value.

     We are asking persons who hold shares of Common Stock beneficially and who have received the Rights distributable with respect to those shares through a broker, dealer, commercial bank, trust company or other nominee, as well as persons who hold certificates of Common Stock directly and prefer to have such institutions effect transactions relating to the Rights on their behalf, to contact the appropriate institution or nominee and request it to effect the transactions for them. In addition, we are asking beneficial owners who wish to obtain a separate Subscription Rights Certificate to contact the appropriate nominee as soon as possible and request that a separate Subscription Rights Certificate be issued.

     Please take prompt action to notify any beneficial owners of Common Stock as to the Rights Offering and the procedures and deadlines that must be followed to exercise their Rights. If you exercise the Over-Subscription Privilege on behalf of beneficial owners of Rights, you will be required to certify to the Subscription Agent and the Company, in connection with the exercise of the Over-Subscription Privilege, as to the aggregate number of Rights that have been exercised pursuant to the Basic Subscription Privilege, whether the Basic Subscription Privilege of each beneficial owner of Rights on whose behalf you are acting has been exercised in full and the number of shares of Common Stock being subscribed for pursuant to the Over-Subscription Privilege by each beneficial owner of Rights on whose behalf you are acting.

     All commissions, fees and other expenses (including brokerage commissions and transfer taxes), other than certain fees and expenses of the Subscription Agent and the Information Agent incurred in connection with the exercise of the Rights will be for the account of the holder of the Rights, and none of such commissions, fees or expenses will be paid by the Company, the Subscription Agent, or the Information Agent. Enclosed are copies of the following documents:

	1.		Prospectus;
	2.		Instruction for Use of BlueLinx Holdings Inc. Subscription Rights Certificates;
	3.		A form of letter that may be sent to your clients for whose accounts you hold shares of Common Stock registered in your name or the name of your nominee, with an attached form of instruction;
	4.		Nominee Holder Certification; and
	5.		A return envelope addressed to Registrar and Transfer Company, the Subscription Agent.

     Your prompt action is requested. To exercise the Rights, you must deliver the properly completed and signed Subscription Rights Certificate, together with the Nominee Holder Certification and payment in full of the total subscription amount that is required for all of the shares subscribed for in the Rights Offering, to the Subscription Agent as described further in the Prospectus. Do not send the Subscription Rights Certificate, Nominee Holder Certification or payment to the Company. The properly completed and signed Subscription Rights Certificate and Nominee Holder Certification, accompanied by full payment of the total subscription amount, must be received by the Subscription Agent, and your payment must clear, by no later than 5:00 p.m., New York City time, on the Expiration Date. Failure to return the properly completed Subscription Rights Certificate and Nominee Holder Certification with the correct payment will result in your not being able to exercise the Rights held in your name on behalf of yourself or other beneficial owners. A Rights holder cannot revoke the exercise of Rights (unless we are required by law to permit revocation). Rights not exercised before 5:00 p.m., New York City time, on the Expiration Date will expire without value.

Very truly yours,
BLUELINX HOLDINGS INC.
