My bottle jack does NOT fit the dimensions.

The Safe Jack Extension Screw Collar (ESC) is a device made from highly durable PLA carbon fiber that wraps around your bottle jack’s extension screw, acting as the universal, secure engagement for our Extensions and Lift Pads. The ESC also provides the operator with 100% available stroke of the jack and maximizes the height to an additional 1.5 inches. Our premade Extension Screw Collars are measured specifically for the bottle jack brands we carry. The 6-ton ESC wraps around a bottle jack extension screw measuring 0.893 - 0.955 inches in diameter. If you have your own bottle jack you wish to use instead, you will need to check if your bottle jack fits these dimensions. Please watch this video for instructions on how to do so.

The ESC is easy to install and remove, taking only a few seconds, and requires no extra tools. Safe Jack ESCs are standard equipment for our Bottle Jack Recovery Kits. They should be applied anytime Extensions or Lift Pads are used for proper fit and maximal stroke.

6 ton screw collar works great.Had to change a leaking tire on 5th wheel on side of road.Works great.

Safe Jack

This is just what I needed for my Jeep Wrangler. It is not too big, nor heavy. I purchased theater components from Safe Jack, I like them. Plus the components are made in the USA. I'm happy with the jack and components.

Needed item

Works as advertised! I gave it and the extensions a test run on my Jeep in the driveway.

This is the difference maker

The heights of the various extensions don't quite add up to what works to jack up my 2018 4Runner with a 2 inch lift and 33" tires. By unscrewing the extension on the jack ram and using this little collar, I get a perfect height when used with the 3" extension and flat pad together. Perfect solution for a few extra bucks

Glad I purchased this it works well with lift pad
