Double bosshead according to Fisher, Premium Line is a laboratory clamp fitting for building stable rod frameworks on the bench. It is made from aluminium alloy with screws of nickel-plated steel and accepts rods up to 16 mm in diameter, supporting secure cross-connections in modular support systems. The Fisher-style double bosshead geometry is intended for everyday apparatus assembly where two rods must be locked at a defined angle without bulky hardware. Supplied as one piece with a net weight of 0,045 kg, the fitting keeps added mass low while remaining robust enough for repeated adjustment of stands, clamps, and holders. This Premium Line component from manufacturer Labbox suits teaching, research, and quality-control laboratories that rely on Fisher-compatible bossheads for glassware, sensors, and general scaffolding. Aluminium alloy construction aids handling and corrosion resistance under normal laboratory conditions, while nickel-plated steel screws provide firm grip on rods. Use it wherever double bossheads and cross-clamp style connectors are required to extend or reconfigure existing rod lattices quickly and repeatably.

Questions about Bosshead, Fisher type, Premium Line
What is this article?
Bosshead, Fisher type, Premium Line is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Labmateriaal.
A bosshead grips the rod. A clamp grips the flask or the condenser, usually through two jaws with cork or vinyl faces. Three-finger and two-finger clamps hold different shapes. The jaw opening is the specification.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
