mm)
No. 191 Series 1 1/2"-2 1/4" (38-57 mm)
"Little Giant" Jack Screws are
very handy for leveling work on planer beds, upright drills, setting up
machinery, and for general use in the toolroom or machine shop.
The jacks will easily lift 1,000 lbs. (455
kg.) or more. No. 190 and No. 191 have 20-pitch screws, and for those
who desire a finer adjustment, the No. F190 has a 40-pitch screw.
An auxiliary pointed screw (D) is supplied,
to be used in place of the screw with swivel cap. Extension base (E) is
furnished for places where it is not possible to obtain a bearing on a
flat surface. Extension V base (F) is for use against a cylindrical form.
