External Heavy Duty Retaining Rings

These rings offer the same features as our Standard Retaining Rings, but are able to handle more force thrown at them. Also the size range on the heavy-duty models is wider than our standard external rings.

Other external retaining rings we offer include Bowed, Push-On, Heavy Duty Push-On and Grip. Contact us today!
