Hi Carol, I’d highly recommend Gripper rods for any staircase not only for wear purposes but, for safety. Gripper rods should be installed with underlay. You should check the pile of your carpet. If you have a short piled carpet I’d recommend short pin gripper as to not catch your toes on the pins when travelling up and down the stairs as this can be painful. However, make sure you get the right gripper rods for the right area. Most professionals should have stock of various gripperods so always mention it to your installer before arrival to avoid disappointment. I hope this helps? Any further questions please feel free to get in contact. All the best and good luck. Scott
