If the LB's are listed for Class II Div 2, then they are listed, period, regardless if they are aluminum or cast iron. Likewise the connectors, and having one listing does not imply having the other.

Oddly enough, Aluminum RMC and associated fittings (Article 344) are not specifically listed for any classified location. They are, however, approved for Class II, Division 2 under Sections 344.10 (A)(3) and 502.10 (B)(1) & (2). Aluminum LBs must be consistent with Section 502.10(B)(4).

Section 344.6 simply requires LBs to be listed although not specifically for Class II, Division 2.

"LFMC" that is not listed is not LFMC. [See Section 350.6]
