President - CEO
FRED LAND
After years of success with Acutech, the makers of Fix-A-Flat, Fred and his business partner Mike Whitaker became concerned about the environmental impact of certain chemicals. In 1998, they decided to start Interlock Industries, the makers of Spray-Lock Premium Eco Adhesives. When not creating innovative products, Fred loves seeing rock concerts with his wife and sons, spending time with his lovely grandchildren and being an avid LEGO Maniac.
