JJ0304 | The JackJaw® 304 Square Post Extractor was developed specifically to make easy work of removing 2" to 2-1/2" diameter square sign posts that are commonly used by department of transportation professionals. It is lightweight (23 lbs) and made of heavy gauge steel plate and tubing. It's patented jaw mechanism provides a positive grip that prevents back and shoulder strain that results from the whiplash of other pullers. The puller features a sturdy lever arm that generates a 16 to 1 mechanical advantage on the stake. This means when the operator pushes down on the handle with 100 lbs, the unit produces an upward force of 1600 lbs on the stake! The pulling force is aligned with the stake shaft, making it easier to pull and does not bend or damage the stake. Since the unit operates by pushing down with the operator's weight, back strain and injury are prevented.

MADE TO LAST

JackJaw® stake extractors are produced in Dayton, OH from heavy gauge steel plate and tubing to withstand everyday job site use. The gripping jaws of the JackJaw® puller are made from case hardened AR400 steel that will last for thousands of pulls. JackJaw® units have a zinc and clear chromate plating for long lasting durability and corrosion resistance. No paint to chip.

When it is necessary, the jaws are easily replaced in the field using common tools. Order jaw kit CA0010 for single bladed link arm models (100 Series, 200 Series), or jaw kit CA0006 for clevis link arm models (300 Series, 400 Series, 500 Series).
