How must the props bind when the front rows engage?

Answer 1

Loose head prop binds outside the tight head's right arm

Tight head prop binds outside the loose head's left arm

Tight head prop may bind on the loose head prop's upper arm

Tight head prop may opt not to bind

All props must bind on the back or side of the opposing props' bodies

Once bound, props may exert upward or downward pressure on opponents

Answer 2

The front rows must crouch so that when they meet, each player's head and shoulders are no lower than the hips. The front rows must interlock ear against ear so that no player's head is next to the head of a team-mate. The front rows crouch and using their outside arm each prop must bind. A loose-head prop must bind on the opposing tight-head prop by placing the left arm inside the right arm of the tight head and gripping the tight-head prop's jersey on the back or side. A tight-head prop must bind on the opposing loose-head prop by placing the right arm outside the left upper arm of the opposing loose-head prop and gripping the loose-head prop's jersey with the right hand only on the back or side. The props must not grip the opponent's chest, arm, sleeve or collar.
