ABBA, Volvo, IKEA, and Swedish meatballs: the Swedes have a history of wonderful exports. With the invention of Woodloc, hardwood floors were changed forever. Just how strong is the glueless Woodloc joint? Well, you can lock two boards together and hang a car from them. This means that gaps in your floor are a thing of the past. Installation is also wonderfully easy whether you're floating, stapling, or gluing down your floor. Watch Woodloc in action here.
