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. If you have your own bottle jack you wish to use instead, you may need a custom ESC. Please watch the step-by-step tutorial video on how to measure your jack to determine whether or not a custom ESC will be necessary. If so, we'll create a custom Extension Screw Collar just for you! Please fill out the form above before placing your order. 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. Videos
