The required height of the pin stack in an IC Cylinder is 23. This height is important because it ensures that the cylinder functions properly and meets the design specifications necessary for effective locking and security. The pin stack height is determined by the design of the cylinder and is critical for achieving the correct tolerances and functionality, such as ensuring that the pins properly align with the shear line when the correct key is inserted. This alignment allows the cylinder to turn and unlock while maintaining security against unauthorized access. The correct height significantly influences how well the lock operates, making it vital for locksmiths to be familiar with these specifications when servicing or installing locks.
