  • Simple and Easy to Install

    Installing Square D Lug Barriers

    Through the design phase, we asked numerous contractors from various regions of the US to spend time with the new barriers prototypes. We wanted to gain valuable feedback on the proposed design for form, fit, ease of installation, and preferences. In most applications, the service entrance barriers install without the use of any tools, providing a simple and intuitive install that is fully capable of retrofit.
