Were committed to making things easier, both for our customers and those they serve. Thats why Southwire decided to upgrade the original ROMEX to the new and improved ROMEX SIMpull NMD90. It not only pulls 50% easier than conventional NMD but also saves a lot of time, with half the effort. In the beginning, Southwires goal was to simply improve NMD usage by making it easier to pull without increasing costs. Where they ended is a revolutionary new grade of NMD. New ROMEX SIMpull NMD90, 50% easier to pull, 100% easier on you. Southwire's ROMEX SIMpull Type NMD90 cables may be used for both exposed work in dry locations or concealed work in dry or damp locations.
