CenterLock™ is a premium vinyl siding with the clean look of wood.

Designed for maximum visual appeal, it features an innovative double-lock panel design that provides enhanced panel rigidity and tight, flat-to-the-wall seam locks. Its unique shape and placement gives CenterLock twice the holding power of ordinary vinyl sidings. In wind resistance tests, CenterLock panels stayed locked in place at wind forces exceeding 150 miles per hour! That means straighter, smoother, more even walls...just like wood siding, but without the headaches of regular maintenance.
