Product Description (for reference only)
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.
The 271 and 281 Lab Jacks have an array of 1/4-20 threaded holes on 1 in. centers. Both the top and bottom plates have four clearance holes used for mounting the Lab Jack to the optical table.
