6 Ton 6" Jack Extension

Safe Jack

  • $ 4700

PN: 37112
UPC: 854185005110

The 6-inch Bottle Jack Extension adds 6 inches of height to the available stroke of a bottle jack. Don't risk your health and safety piling up unstable wood or rock under the jack; start lifting safer! Multiple Extensions can be stacked to increase the height of the hydraulic cylinder (ram.) All of our made-in-the-USA Extensions and Lift Pads feature a solid steel shaft.

Safe Jack utilizes the Extension Screw Collar to create a secure engagement for the Extensions and Lift Pads, as well as to maximize the available stroke to an additional 1.5 inches. These premade Extension Screw Collars are measured specifically for the bottle jack brands we carry. If you have your own bottle jack you wish to use instead, you may need to purchase a Custom Extension Screw Collar. If you opt out of purchasing a Custom Extension Screw Collar altogether, the adapters may still work, but you will not achieve the additional 1.5 inches of stroke. The 6-ton adapters will fit over a bottle jack saddle diameter of 1.25 inches (31.75 mm) or less. If the hydraulic cylinder (ram) is significantly smaller than 1.25 inches, we advise against using the adapters without an Extension Screw Collar, as the point of engagement will be unstable.
