Arm

An R6 arm on Roblox is a brick that is part of a humanoid that goes on the left and right of your Torso. An arm is precisely 1 unit wide, 1 unit long, and 2 units tall. A package or bundle comes with a left arm and a right arm.

Trivia

 * Robloxians carry tools and weapons with their right hand, which involves removing the right hand will make a user unable to use a Tool. HopperBins, however, they do not need an arm to do something.
 * The arms can go through a brick that has the CanCollide function enabled, since arms have this value off.
