The HE Williams MX Series is a solid linear slot family in 2” and 4” apertures. With solid build quality, great lead times and competitive pricing, the MX is a strong option. But what the MX really demonstrates is Williams focus on service. Service to the specifier, but also service to the reps, distributors, and contractors along the project path. By making a software-based solution like this, HEW has made it that much easier to make sure what you were expecting is what shows up on-site, with MANY fewer steps.
