Ladies and Gentlemen:

We have acted as special Pennsylvania counsel to Baldwin Hardware Corporation, a Pennsylvania corporation (the “Pennsylvania Guarantor”), which is a subsidiary of Spectrum Brands, Inc., a Delaware corporation (“Spectrum”), in connection with the Registration Statement on Form S-4 (the “Registration Statement”) filed by Spectrum, SB/RH Holdings, LLC, and the subsidiaries of Spectrum listed in the Registration Statement, including the Pennsylvania Guarantor, with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement relates to the issuance by Spectrum of certain Exchange Notes guaranteed by SB/RH Holdings, LLC, the Pennsylvania Guarantor, and certain other subsidiaries of Spectrum listed in the Registration Statement (collectively, the “Guarantors”) in exchange for the same aggregate principal amount of the Initial Notes which are not registered under the Securities Act.

The Initial Notes were, and the Exchange Notes will be, issued under an Indenture dated as of November 16, 2012, initially between Spectrum Brands Escrow Corp., the issuer of the Initial Notes, and U.S. Bank National Association, as trustee (the “Indenture”). As of December 17, 2012, Spectrum and the Guarantors, including the Pennsylvania Guarantor, entered into a Supplemental Indenture with U.S. Bank National Association, as trustee (the “Supplemental Indenture”), under which Spectrum agreed unconditionally to assume the obligations of Spectrum Brands Escrow Corp. under the Initial Notes and the Indenture and the Guarantors agreed to become guarantors under the Indenture and to be bound by the terms of the Indenture.

All capitalized terms used and not otherwise defined herein shall have the meanings assigned to such terms in the Indenture. We have assumed, with your permission, that (i) except for the Supplemental Indenture, the Indenture has not been further amended, modified, or supplemented and (ii) the Exchange Notes will be issued pursuant to the Indenture and otherwise in compliance with the provisions of the Indenture.

In connection with this opinion, we have examined copies, identified to our satisfaction, of fully executed counterparts of the documents listed on Exhibit A attached hereto (the “Documents”). We have also examined (i) the articles of incorporation of the Pennsylvania Guarantor (the “Articles”) as certified by the Secretary of the Department of State for the Commonwealth of Pennsylvania (the “Secretary of

State”) on November 19, 2013; (ii) the bylaws of the Pennsylvania Guarantor as certified by the Secretary of the Pennsylvania Guarantor on December 2, 2013 (the “Bylaws,” and together with the Articles, the “Pennsylvania Guarantor Organizational Documents”); (iii) the Corporate Resolutions of the Pennsylvania Guarantor dated as of December 17, 2012; (iv) a certificate of good standing of the Pennsylvania Guarantor certified by the Secretary of State on November 26, 2013 (the “Certificate of Good Standing”); (v) that certain Omnibus Secretary’s Certificate of the Pennsylvania Guarantor and certain other subsidiaries of Spectrum delivered in connection with the execution and delivery of the Documents, from Nathan E. Fagre, as Vice President and Secretary of the Pennsylvania Guarantor dated as of December 2, 2013 (the “Omnibus Certificate”); and (vi) the Registration Statement.

In rendering the opinions expressed below, we have assumed, with your permission and without independent investigation:

a. the valid existence and good standing in the jurisdiction of its organization of each party to the Documents (other than the Pennsylvania Guarantor);

b. the due authorization, execution and delivery of the Documents by each party thereto (other than the Pennsylvania Guarantor);

c. the power and authority of each party to the Documents (other than the Pennsylvania Guarantor) to execute, deliver and perform its obligations under the same, and that such execution, delivery and performance do not conflict with, contravene, violate or constitute a default under such party’s certificate or articles of incorporation, bylaws or other organizational documents,

d. the execution, delivery and performance of its respective obligations under each Document to which it is a party by each party to the Documents do not conflict with, contravene, violate or constitute a default under (i) any indenture, instrument or other agreement to which such party or its property or assets is subject or any contractual or legal restriction having applicability to such party or such property or assets, (ii) any rule, law or regulation of any court or regulatory or governmental authority to which such party (other than the Pennsylvania Guarantor) is subject or (iii) any writ, order, judgment or decree of any court or regulatory or governmental authority to which such party is subject or by which any of its properties or assets are bound;

e. the authority of all individuals signing the Documents on behalf of the parties thereto (other than the Pennsylvania Guarantor);

f. the legal capacity of all natural persons, including natural persons acting on behalf of a business entity; and

g. that there are no records, agreements or understandings between any of the parties to the Documents that would alter the agreements set forth therein.

We have relied on the Omnibus Certificate and have assumed that the directors of the Pennsylvania Guarantor executing the unanimous written consent referred to therein were duly elected by the sole shareholder of the Pennsylvania Guarantor in accordance with applicable laws and the

Pennsylvania Guarantor Organizational Documents, that the directors of the Pennsylvania Guarantor executing the aforesaid unanimous written consent comprise all of the directors of the Pennsylvania Guarantor and that the officers of the Pennsylvania Guarantor whose incumbency is certified in the Omnibus Certificate have been duly elected or appointed in accordance with applicable laws and the Pennsylvania Guarantor Organizational Documents.

We have also assumed the genuineness of all signatures, the authenticity of all writings, certificates, instruments and records submitted to us as originals, the conformity to originals of all such writings, certificates, instruments and records submitted to us as certified, conformed or photostatic copies, the authenticity of the originals of such copies, and the truthfulness of all statements of fact set forth therein.

Based on the foregoing and in reliance thereon, and subject to the limitations, qualifications, and exceptions set forth below, we are of the opinion that:

1. The Pennsylvania Guarantor is a corporation validly existing and in good standing under Pennsylvania law and has all requisite power and authority and to execute, deliver, and perform all of its guarantee obligations under the Indenture.

2. The Supplemental Indenture has been duly authorized, executed and delivered by the Pennsylvania Guarantor.

3. The Pennsylvania Guarantor has duly authorized its guarantee of the Exchange Notes.

4. The execution, delivery and performance by the Pennsylvania Guarantor of the Supplemental Indenture, including its guarantee of the Exchange Notes under the Indenture, does not violate any provision of statutory law or regulation of the Commonwealth of Pennsylvania applicable to the Pennsylvania Guarantor, or violate any provision of the Pennsylvania Guarantor Organizational Documents.

The opinions set forth above are subject to the following limitations, qualifications, and exceptions:

(A) In this opinion, any reference to Pennsylvania law means the Pennsylvania Business Corporation Law of 1988, as amended, and those laws, statutes, rules and regulations of the Commonwealth of Pennsylvania which, in our experience, are normally applicable to transactions of the type contemplated by the Documents and would normally be applicable to domestic corporations transacting business in Pennsylvania that are not engaged in regulated business activities (other than state blue sky laws, securities laws, and antifraud laws), but without having made any special investigation concerning the applicability of any other law, statute, rule or regulation.

(B) The foregoing opinions are strictly limited to the matters stated herein, and no other or more extensive opinion is intended or implied or to be inferred beyond the matters expressly stated herein.

(G) We have made no examination of, and express no opinion as to, the business, operations or financial condition of the Pennsylvania Guarantor or any other individual or entity or the effect thereon of the transactions contemplated by the Documents.

We are not expressing any opinion as to the effect on the Documents if any such assumptions should be inaccurate or as to any matter for which an express opinion is not provided herein.
