Newport 271 Lab Jack / Vertical Translation Stage, Heavy Duty

Description

Newport model 271 heavy duty lab jack, 1.75" vertical travel range, 200 lbs load capacity, imperial and metric compatible. Excellent mechanical and cosmetic condition.
(From manufacturer's website) The model 271 Lab Jack is 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 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.
