High Load Lab Jack, 6.5 x 9.5 inch, 300 lb. Load Capacity

The model 281 Lab Jack is uniquely designed to provide smooth, stable height adjustment and high load capacity. Conventional scissors and dual-pantograph labjacks lift by decreasing the distance between crossed members and are inherently less stable at higher elevations. In contrast, Newport’s innovative labjack 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. The 281 Lab Jack is both English and Metric compatible. The top plate has an array of 1/4-20 tapped holes on 1 in. centers while the bottom plate has an array of M6 holes on 25-mm centers. Both the top and bottom plates have four clearance slots used for mounting the Lab Jack to the optical table.
