About Us

Thinking outside the (utility) box!

Our Story

“Having a background as manufacturers’ representatives, we’ve witnessed first-hand our customers’ struggles to solve this age-old problem of protecting fiberglass box pads from lawnmower and weed whacker damage. Time after time, our customers would go out to patch and repair the same locations only to eventually spend even more time and money landscaping around the problem locations. Over the years, we’ve seen all kinds of contraptions and ideas intended to repair damaged utility boxes. While many of these efforts were effective for a period of time, the end result was often unsightly and quite expensive. We knew there had to be a better way. We made it our top goal to create a protection system that checked off all of our customers’ needs…and was affordable and simple to use.” – Sean Dunham, CEO & Founder
