If it's not easy, it's not better. That's why Wiremold® 4000® Designer Series™ Raceway includes time-saving features to get you off the job and on to the next. Sooner. A base with an integrated divider allows for easy installation. Modular design and Adjust-to-Fit couplings mean less cutting. You can bypass large and small obstacles with obstacle avoidance fittings. And it accepts all standard NEMA faceplates and devices. The DS4000 raceway comes prewired as well, saving additional time and labor. There's one-third more capacity, yet fewer parts, so you get more. And less.
