The Knurled baby pin is a crucial feature of this boom, as it ensures that whatever is being mounted will stay securely in place. This is especially important for heavy or delicate equipment, as it prevents any movement or slippage during use. Additionally, the V-shaped brass brakes provide a strong and stable 3-point contact, further ensuring the stability of the mounted equipment. The thick threaded collars also play a role in keeping everything in place, as they provide a solid bite from the t-handles and set screws.
