General Notes:
This is an economy jack which allows for coarse adjustment of height only.

At this price point, these are not precision jacks. They are made for holding up objects where loose height tolerances (i.e., a couple millimeters) and the possibility of a very slight wobble are allowable.

They are still very useful in a huge variety of lab situations and are a popular item.

Safety Reminders:

1. Do not use this jack to support containers of poisonous, corrosive, boiling, or hot/molten materials.

2. * We recommend you put no more than 35 lbs on the jack when it's at or near its maximum height.

3. Do not place a precarious, moving, or unbalanced load on the jack.

4. Do not try to adjust the height after weight has been placed on the jack.  The laboratory jack should be adjusted to the proper height before putting weight on it.
 
5. Do not use any laboratory jack to support anything that someone's life or safety depends on.

6. Do not step or stand on the laboratory jack.
