Will give a stronger, less-forgiving hold than nailed down because of its two-pronged construction.
One side and one end of the plank have a groove, the other side and end have a tongue (protruding wood along an edge’s center).
The tongue and groove fit snugly together, thus joining or aligning the planks, and are not visible once joined.
Depending on flooring type, tongue-and-groove flooring can be installed by:
Click Lock | Snap Lock | VersaLock™ System
Patented click lock system – no glue or nails required
A “click” floor is similar to tongue-and-groove, but instead of fitting directly into the groove, the board must be angled or “tapped” in to make the curved or barbed tongue fit into the modified groove.
Clean installation – avoid the mess of using glue
Repairs are easier, since you can remove the damaged planks without worrying about destroying the locking “tongues.”
