Premium Swivel Boss Head with 360° Rotation, Black, 16mm Rods

This premium swivel bosshead is made from high-grade zinc alloy with a non-toxic black powder coating finish. It is non-ferrous and rust-free, designed for demanding laboratory applications requiring heavy load support and high torsional strength. The bosshead holds rods orthogonally at 90 degrees and features 360-degree swivel rotation for flexible positioning. The thicker casting design prevents torque damage under heavy loads. It accepts rods up to 16mm in diameter in the smaller opening and up to 19mm in the larger opening, secured with 7mm clamping screws that are thicker than standard for enhanced grip strength. Suitable for professional, educational, and home laboratory setups.
