The adapter clamps onto the shaft of your putter and is the interface between you and the Arc Master.
Having multiple adapters allows you to quickly swap between putters without having to remove it each time. This allows for a more seamless practice session and an increased shot count per hour.
The 'UA' is made from a durable polymer and has two soft grip pads on the interior that prevent damage to the putter shaft.
Two M4 Stainless Steel machine screws provide the clamping pressure needed to ensure a robust connection.
