    Description

    Newport Lab Jack Model 281, 76 mm Travel, 6.5 x 9.5 in. Platform, 300 lb., 1/4-20 and M6
    Great used condition! Works smoothly! There are a few minor scratches. No box. Weighs 12.6 lbs
    The 281 Lab Jack is uniquely designed to provide smooth, stable 76 mm height adjustment and a high 1334 N load capacity.  It features 1/4-20 threads on the top plate and M6 threads on the bottom plate, and can be slot mounted with either plate on the top.
    Innovative Stable Mechanism
    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.
    Large Vertical Adjustment Range
    The 281 offers 3 full inches of vertical adjustment with 48 revolutions of the adjustment knob.
    Both 1/4-20 and M6 Threads Included
    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 optical tables.
