Backrake 2 is a period 12 backrake that was created by David Buckingham. It works by having a front puffer made up of two lightweight spaceships, a middleweight spaceship, and a B-heptomino (much like puffer 2) send debris back to another lightweight and middleweight spaceship, which turn the debris into a backward-moving glider.

Three copies of this backrake feature in total aperiodic.
