 This is Tyler Smith, General Manager of Yavapai Block, and I'm standing on the Great Wall of China. And yes, it's made of VersaLock Lock. If you want your next building project to stand the test of time, come visit us at Yavapai Block. We're just off Highway 89 off Industrial Way. You'll be amazed at the colors and textures we can create with strong and safe VersaLock from Yavapai Block. Call 445-4340 or check out our website at yavapiblock.com.
