The Keyway Curb System was developed by William Harger in 1986. Having worked for CDOT as a project manager as well as numerous general contractors, Bill struck out on his own. He relied on past experiences to aid his development of a better mousetrap... a better curb system. Though having passed, our family relies on the values and instincts he instilled upon us as we carry on his legacy.
