The XL Thick Table Clamp mounts onto thicker (< 17" or 44 cm) tables and provides excellent stability as a base. The clamp is built with an aluminum die-cast body, making it sturdy and lightweight. The anti-slip rubber pad is attached to the clamp jaw by a mechanical interlocking method to offer extra stability of grip. The clamp has a built-in female socket that can receive a 5/8" (16 mm) hex stud. An additional spring locking system in the hex receiver prevents attachments from falling out when not fully secured by the screw locking mechanism. The Super Convi Clamp works well with the Super Knuckle Arm, the Max Arm, and the Articulated Arm. The user-friendly Clamp is easily secured and removed efficiently.
