INON Arm series is manufactured by machined lightweight aluminum alloy to benefit high-precision, light weight and extraordinary strength.
Unlike molding or casting, this manufacturing system obtains accuracy of "0.01mm" providing very smooth fitting between ball-joint and clamp.
The diameter of ball-joint is 24mm/0.9", equipping O-Ring providing firm and reliable clamping but you never feel any stress when you adjust arm position by loosening a clamp.
INON Arm O-Ring is made of ozone-proof and weather-proof silicon rubber.
