This extendable scissor jack is manufactured from rust- and corrosion-resistant 304 stainless steel and features an ABS molded handle with a fine-threaded adjustment rod for precise height control. The stainless steel body is autoclavable and tolerant of many chemicals, and rubber slip-proof compression feet prevent bench scratches. When compact the jack measures 2.5" x 10"; at full extension it measures 11" x 10" with a 9.75" x 9.75" working top surface. Maximum load is 88lbs. A single-piece base provides torsional rigidity under load. Well suited to physical, chemical, and biological experiments and to machine, model, or fabrication shops.
