Specially Designed for Manhole Lifts When lifting manholes, it's important to use properly rated pins. Pins that are designed for lifting manholes are made to take different load angles than just standard eye bolts. We offer a variety of pins in different diameters and lengths. The M&W pins feature a toggle on the end that helps to keep the pin from sliding out. Manhole pins should be used in pairs only, and always use properly rated lifting slings and rigging components.
