Description
The Boss Head Clamp, Jumbo Heavy Duty, also known as a jumbo bosshead or heavy-duty retort stand clamp holder, is designed for connecting compatible rods, clamps and support apparatus in laboratory setups. This jumbo bosshead can be used with retort stands, condenser clamps and other compatible laboratory support equipment where a strong screw-and-block style connection is required. The boss head is made from heavy-duty die-cast iron and painted with a black finish as listed, making it suitable for routine school, university and laboratory support applications.
The screw and block style connection is designed to support a good amount of weight when correctly fitted to a stable support stand and compatible rod system. This item is listed as holding rods up to 25 mm, making it suitable for larger laboratory support setups compared with smaller standard bossheads. Users should confirm rod diameter, clamp type, apparatus weight, stand stability, load balance and experiment layout before ordering or use. Do not overload the bosshead, overtighten onto glassware or use with unstable stand assemblies. Heavy, elevated or offset apparatus should be supported carefully to reduce tipping, slipping or breakage risk.
This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the jumbo heavy-duty boss head clamp only. Retort stand, support rods, condenser clamps, burette clamps, glassware, condensers and additional laboratory accessories are not included unless specified separately.
LabChoice Australia supplies Jumbo Heavy-Duty Boss Head Clamps and laboratory support accessories for school science laboratories, university teaching laboratories, research laboratories and educational facilities requiring strong support components for secure apparatus setup.
