The JackJaw502 is the fast, easy and safe way to extract 3/4'' to 1 1/4'' tent stakes or rebar from hard ground conditions or stakes longer than 42''. These conditions generally result from tight calichi/kalichi clay (found in Arizona) or frozen ground. This stake puller prevents bending the stakes and damage to asphalt by pulling stakes straight out of any surface. This rugged all steel tent stake and rebar puller weighs 39lbs. It is designed to handle the massive loads extracting stakes from these conditions. It?s patented jaw mechanism provides a positive grip that prevents back and shoulder strain that results from the whiplash of other pullers. The sturdy extendable lever arm generates a 20 to 1 mechanical advantage with the handle recessed, and up to 28 to 1 with the handle extended. A 100lb down force on the handle generates a 2800lb upward force and a 5600lb gripping force on the stake. Tilted stakes? No problem! Just lean the JackJaw to align with the stake. With the optional stake bar adapter (AC0009), the JackJaw502 easily pulls stakes from stake bars or flat base plates used in clear span tents.
