2x4

Common framing timber

A 2x4 is a piece of lumber nominally two inches by four inches in cross-section, though actual dimensions are smaller due to milling and drying.

It's a fundamental building material for framing walls, floors, and roofs: We need about forty 2x4s for the deck.

The term extends to anything made from such lumber, and informally to a plank used as a weapon or attention-getter: Sometimes you have to hit them with a 2x4 to get their attention.
