When you need to move just about anything with posts or even without posts these dollies are real people savers! They are compact triangular shaped dollies with a cup center; often called cup dollies or cup casters. One dolly is placed under each post or leg of the article you intend to move; once all posts have dollies you simply roll your article through doorways, onto elevators, down the street, into the truck, or across the room! The swivel wheels and tripod wheel arrangement allow the article to be moved in any direction; even top heavy articles go where you want them too safely and securely.
Cast semi-steel with 2" deep well, measuring 5" at the top and 3-3/16" at the bottom. Clearance is 5/8" from the floor.
