Click-Lock
A tongue-and-groove plank profile that snaps together without nails, glue, or fasteners.
Click-lock (sometimes called angle-tap or fold-down lock) is the dominant residential install method for LVP, laminate, and engineered hardwood. Planks snap together along their long and short edges using a precision-milled tongue-and-groove profile.
Click-lock floors install as floating floors — they're not attached to the subfloor, just held in place by their own weight and the perimeter trim. This makes them fast to install (an experienced crew runs 50+ sqft per hour per installer) and easy to repair (lift and replace one plank at a time).
The trade-off vs. glue-down: click-lock can sound hollower underfoot and is less stable in commercial high-traffic environments. For residential, click-lock is almost always the right call.
