The 4-1/2" Grip Head, also known as a lollipop, features an all-aluminum construction attached to a junior 1-1/8" (28mm) stud and receiver. It comes equipped with two different sized V-shaped jaws designed to accommodate accessories with a 5/8" or 3/8" mounting stud or tubing. These V-shaped jaws have teeth that securely grip any item placed between them. The grip head utilizes a rubber friction disc, ensuring long-lasting durability and providing users with strong, reliable locking and precise control. When you need to crank down on a large overhead frame to hold it in place this is the grip head for the job. It is designed to convert a junior stand with a combo head into an overhead stand.
