I'm looking for several items related to malleable iron products and accessories. Specifically, I need reducing tees and elbows with NPT threads, all UL listed for safety compliance. Additionally, I require UL/FM approved pipe hangers made from electrogalvanized materials, suitable for certain pipe specifications, along with electrogalvanized ceiling flanges that fit M10 threads. Please provide me with the pricing and availability for these products in the specified quantities. It's essential that all items meet UL listings to ensure they adhere to required safety standards. Looking forward to your prompt response with the details!
