High Load Lab Jack, 4.375 x 6.5 inch, 200 lb Load Capacity

Model 271 and 281 Lab Jacks are uniquely designed to provide smooth, stable height adjustment and high load capacity.
Conventional scissors and dual-pantograph jacks lift by decreasing the distance between crossed members and are inherently less stable at higher elevations. In contrast, Newport s innovative design employs three orthogonal hinges that straighten to form a box, becoming more stable with increasing height. The side mounted height adjustment controls a stout drive screw connecting the pivot pins of the broad side hinges. The end hinge prevents tilting or swaying and ensures only vertical motion
